[PATCH AUTOSEL 6.5 04/31] ASoC: simple-card: fixup asoc_simple_probe() error handling

[Sasha Levin]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

[ Upstream commit 41bae58df411f9accf01ea660730649b2fab1dab ]

asoc_simple_probe() is used for both "DT probe" (A) and "platform probe"
(B). It uses "goto err" when error case, but it is not needed for
"platform probe" case (B). Thus it is using "return" directly there.

	static int asoc_simple_probe(...)
	{
 ^		if (...) {
 |			...
(A)			if (ret < 0)
 |				goto err;
 v		} else {
 ^			...
 |			if (ret < 0)
(B)				return -Exxx;
 v		}

		...
 ^		if (ret < 0)
(C)			goto err;
 v		...

	err:
(D)		simple_util_clean_reference(card);

		return ret;
	}

Both case are using (C) part, and it calls (D) when err case.
But (D) will do nothing for (B) case.
Because of these behavior, current code itself is not wrong,
but is confusable, and more, static analyzing tool will warning on
(B) part (should use goto err).

To avoid static analyzing tool warning, this patch uses "goto err"
on (B) part.

[PATCH AUTOSEL 6.5 07/31] ASoC: fsl-asoc-card: use integer type for fll_id and pll_id

[Sasha Levin]

From: Shengjiu Wang <shengjiu.wang@nxp.com>

[ Upstream commit 2b21207afd06714986a3d22442ed4860ba4f9ced ]

As the pll_id and pll_id can be zero (WM8960_SYSCLK_AUTO)
with the commit 2bbc2df46e67 ("ASoC: wm8960: Make automatic the
default clocking mode")

Then the machine driver will skip to call set_sysclk() and set_pll()
for codec, when the sysclk rate is different with what wm8960 read
at probe, the output sound frequency is wrong.

So change the fll_id and pll_id initial value, still keep machine
driver's behavior same as before.

[PATCH AUTOSEL 6.5 07/31] ASoC: fsl-asoc-card: use integer type for fll_id and pll_id

[Sasha Levin]

From: Shengjiu Wang <shengjiu.wang@nxp.com>

[ Upstream commit 2b21207afd06714986a3d22442ed4860ba4f9ced ]

As the pll_id and pll_id can be zero (WM8960_SYSCLK_AUTO)
with the commit 2bbc2df46e67 ("ASoC: wm8960: Make automatic the
default clocking mode")

Then the machine driver will skip to call set_sysclk() and set_pll()
for codec, when the sysclk rate is different with what wm8960 read
at probe, the output sound frequency is wrong.

So change the fll_id and pll_id initial value, still keep machine
driver's behavior same as before.

[PATCH AUTOSEL 6.5 08/31] ASoC: core: Do not call link_exit() on uninitialized rtd objects

[Sasha Levin]

From: Amadeusz Sławiński <amadeuszx.slawinski@linux.intel.com>

[ Upstream commit dd9f9cc1e6b9391140afa5cf27bb47c9e2a08d02 ]

On init we have sequence:

	for_each_card_prelinks(card, i, dai_link) {
		ret = snd_soc_add_pcm_runtime(card, dai_link);

	ret = init_some_other_things(...);
	if (ret)
		goto probe_end:

	for_each_card_rtds(card, rtd) {
		ret = soc_init_pcm_runtime(card, rtd);

probe_end:

while on exit:
	for_each_card_rtds(card, rtd)
		snd_soc_link_exit(rtd);

If init_some_other_things() step fails due to error we end up with
not fully setup rtds and try to call snd_soc_link_exit on them, which
depending on contents on .link_exit handler, can end up dereferencing
NULL pointer.

[PATCH AUTOSEL 6.5 10/31] Input: i8042 - add Fujitsu Lifebook E5411 to i8042 quirk table

[Sasha Levin]

From: Szilard Fabian <szfabian@bluemarch.art>

[ Upstream commit 80f39e1c27ba9e5a1ea7e68e21c569c9d8e46062 ]

In the initial boot stage the integrated keyboard of Fujitsu Lifebook E5411
refuses to work and it's not possible to type for example a dm-crypt
passphrase without the help of an external keyboard.

i8042.nomux kernel parameter resolves this issue but using that a PS/2
mouse is detected. This input device is unused even when the i2c-hid-acpi
kernel module is blacklisted making the integrated ELAN touchpad
(04F3:308A) not working at all.

Since the integrated touchpad is managed by the i2c_designware input
driver in the Linux kernel and you can't find a PS/2 mouse port on the
computer I think it's safe to not use the PS/2 mouse port at all.

[PATCH AUTOSEL 6.5 11/31] Input: goodix - ensure int GPIO is in input for gpio_count == 1 && gpio_int_idx == 0 case

[Sasha Levin]

From: Hans de Goede <hdegoede@redhat.com>

[ Upstream commit 423622a90abb243944d1517b9f57db53729e45c4 ]

Add a special case for gpio_count == 1 && gpio_int_idx == 0 to
goodix_add_acpi_gpio_mappings().

It seems that on newer x86/ACPI devices the reset and irq GPIOs are no
longer listed as GPIO resources instead there is only 1 GpioInt resource
and _PS0 does the whole reset sequence for us.

This means that we must call acpi_device_fix_up_power() on these devices
to ensure that the chip is reset before we try to use it.

This part was already fixed in commit 3de93e6ed2df ("Input: goodix - call
acpi_device_fix_up_power() in some cases") by adding a call to
acpi_device_fix_up_power() to the generic "Unexpected ACPI resources"
catch all.

But it turns out that this case on some hw needs some more special
handling. Specifically the firmware may bootup with the IRQ pin in
output mode. The reset sequence from ACPI _PS0 (executed by
acpi_device_fix_up_power()) should put the pin in input mode,
but the GPIO subsystem has cached the direction at bootup, causing
request_irq() to fail due to gpiochip_lock_as_irq() failure:

[    9.119864] Goodix-TS i2c-GDIX1002:00: Unexpected ACPI resources: gpio_count 1, gpio_int_idx 0

[    9.327840] gpio gpiochip0: (INT3453:00): gpiochip_lock_as_irq: tried to flag a GPIO set as output for IRQ

[    9.327912] Goodix-TS i2c-GDIX1002:00: request IRQ failed: -5

Fix this by adding a special case for gpio_count == 1 && gpio_int_idx == 0
which adds an ACPI GPIO lookup table for the int GPIO even though we cannot
use it for reset purposes (as there is no reset GPIO).

Adding the lookup will make the gpiod_int = gpiod_get(..., GPIOD_IN) call
succeed, which will explicitly set the direction to input fixing the issue.

Note this re-uses the acpi_goodix_int_first_gpios[] lookup table, since
there is only 1 GPIO in the ACPI resources the reset entry in that
lookup table will amount to a no-op.

[PATCH AUTOSEL 6.5 12/31] workqueue: Fix UAF report by KASAN in pwq_release_workfn()

From: Zqiang <qiang.zhang1211@gmail.com>

[ Upstream commit 643445531829d89dc5ddbe0c5ee4ff8f84ce8687 ]

Currently, for UNBOUND wq, if the apply_wqattrs_prepare() return error,
the apply_wqattr_cleanup() will be called and use the pwq_release_worker
kthread to release resources asynchronously. however, the kfree(wq) is
invoked directly in failure path of alloc_workqueue(), if the kfree(wq)
has been executed and when the pwq_release_workfn() accesses wq, this
leads to the following scenario:

Hello Sasha,  the pwq_release_worker only exists in the V6.6 kernel,
the previous versions of kernels do not use this mechanism.

[PATCH AUTOSEL 6.5 13/31] ALSA: usb-audio: Fix microphone sound on Opencomm2 Headset

[Sasha Levin]

From: WhaleChang <whalechang@google.com>

[ Upstream commit 6a83d6f3bb3c329a73e3483651fb77b78bac1878 ]

When a Opencomm2 Headset is connected to a Bluetooth USB dongle,
the audio playback functions properly, but the microphone does not work.

In the dmesg logs, there are messages indicating that the init_pitch
function fails when the capture process begins.

The microphone only functions when the ep pitch control is not set.

Toggling the pitch control off bypasses the init_piatch function
and allows the microphone to work.

[PATCH AUTOSEL 6.5 14/31] net: sched: cls_u32: Fix allocation size in u32_init()

[Sasha Levin]

From: "Gustavo A. R. Silva" <gustavoars@kernel.org>

[ Upstream commit c4d49196ceec80e30e8d981410d73331b49b7850 ]

commit d61491a51f7e ("net/sched: cls_u32: Replace one-element array
with flexible-array member") incorrecly replaced an instance of
`sizeof(*tp_c)` with `struct_size(tp_c, hlist->ht, 1)`. This results
in a an over-allocation of 8 bytes.

This change is wrong because `hlist` in `struct tc_u_common` is a
pointer:

net/sched/cls_u32.c:
struct tc_u_common {
        struct tc_u_hnode __rcu *hlist;
        void                    *ptr;
        int                     refcnt;
        struct idr              handle_idr;
        struct hlist_node       hnode;
        long                    knodes;
};

So, the use of `struct_size()` makes no sense: we don't need to allocate
any extra space for a flexible-array member. `sizeof(*tp_c)` is just fine.

So, `struct_size(tp_c, hlist->ht, 1)` translates to:

sizeof(*tp_c) + sizeof(tp_c->hlist->ht) ==
sizeof(struct tc_u_common) + sizeof(struct tc_u_knode *) ==
						144 + 8  == 0x98 (byes)
						     ^^^
						      |
						unnecessary extra
						allocation size

$ pahole -C tc_u_common net/sched/cls_u32.o
struct tc_u_common {
	struct tc_u_hnode *        hlist;                /*     0     8 */
	void *                     ptr;                  /*     8     8 */
	int                        refcnt;               /*    16     4 */

	/* XXX 4 bytes hole, try to pack */

	struct idr                 handle_idr;           /*    24    96 */
	/* --- cacheline 1 boundary (64 bytes) was 56 bytes ago --- */
	struct hlist_node          hnode;                /*   120    16 */
	/* --- cacheline 2 boundary (128 bytes) was 8 bytes ago --- */
	long int                   knodes;               /*   136     8 */

	/* size: 144, cachelines: 3, members: 6 */
	/* sum members: 140, holes: 1, sum holes: 4 */
	/* last cacheline: 16 bytes */
};

And with `sizeof(*tp_c)`, we have:

	sizeof(*tp_c) == sizeof(struct tc_u_common) == 144 == 0x90 (bytes)

which is the correct and original allocation size.

Fix this issue by replacing `struct_size(tp_c, hlist->ht, 1)` with
`sizeof(*tp_c)`, and avoid allocating 8 too many bytes.

The following difference in binary output is expected and reflects the
desired change:

[PATCH AUTOSEL 6.5 15/31] arm64: dts: imx93: add the Flex-CAN stop mode by GPR

[Sasha Levin]

From: Haibo Chen <haibo.chen@nxp.com>

[ Upstream commit 23ed2be5404da7cee6a519fa69bf22d0f69da4e4 ]

imx93 A0 chip use the internal q-channel handshake signal in LPCG
and CCM to automatically handle the Flex-CAN stop mode. But this
method meet issue when do the system PM stress test. IC can't fix
it easily. So in the new imx93 A1 chip, IC drop this method, and
involve back the old way，use the GPR method to trigger the Flex-CAN
stop mode signal. Now NXP claim to drop imx93 A0, and only support
imx93 A1. So here add the stop mode through GPR.

This patch also fix a typo for aonmix_ns_gpr.

[PATCH AUTOSEL 6.5 16/31] can: flexcan: remove the auto stop mode for IMX93

[Sasha Levin]

From: Haibo Chen <haibo.chen@nxp.com>

[ Upstream commit 63ead535570f13d0e06fda3f2d020c8f5394e998 ]

IMX93 A0 chip involve the internal q-channel handshake in LPCG and
CCM to automatically handle the Flex-CAN IPG STOP signal. Only after
FLEX-CAN enter stop mode then can support the self-wakeup feature.
But meet issue when do the continue system PM stress test. When config
the CAN as wakeup source, the first time after system suspend, any data
on CAN bus can wakeup the system, this is as expect. But the second time
when system suspend, data on CAN bus can't wakeup the system. If continue
this test, we find in odd time system enter suspend, CAN can wakeup the
system, but in even number system enter suspend, CAN can't wakeup the
system. IC find a bug in the auto stop mode logic, and can't fix it easily.
So for the new imx93 A1, IC drop the auto stop mode and involve the
GPR to support stop mode (used before). IC define a bit in GPR which can
trigger the IPG STOP signal to Flex-CAN, let it go into stop mode.
And NXP claim to drop IMX93 A0, and only support IMX93 A1. So this patch
remove the auto stop mode, and add flag FLEXCAN_QUIRK_SETUP_STOP_MODE_GPR
to imx93.

[PATCH AUTOSEL 6.5 18/31] irqchip/gic-v3: Enable non-coherent redistributors/ITSes DT probing

[Sasha Levin]

From: Lorenzo Pieralisi <lpieralisi@kernel.org>

[ Upstream commit 3a0fff0fb6a3861fa05416f21858cf0c75cbf944 ]

The GIC architecture specification defines a set of registers
for redistributors and ITSes that control the sharebility and
cacheability attributes of redistributors/ITSes initiator ports
on the interconnect (GICR_[V]PROPBASER, GICR_[V]PENDBASER,
GITS_BASER<n>).

Architecturally the GIC provides a means to drive shareability
and cacheability attributes signals and related IWB/OWB/ISH barriers
but it is not mandatory for designs to wire up the corresponding
interconnect signals that control the cacheability/shareability
of transactions.

Redistributors and ITSes interconnect ports can be connected to
non-coherent interconnects that are not able to manage the
shareability/cacheability attributes; this implicitly makes
the redistributors and ITSes non-coherent observers.

So far, the GIC driver on probe executes a write to "probe" for
the redistributors and ITSes registers shareability bitfields
by writing a value (ie InnerShareable - the shareability domain the
CPUs are in) and check it back to detect whether the value sticks or
not; this hinges on a GIC programming model behaviour that predates the
current specifications, that just define shareability bits as writeable
but do not guarantee that writing certain shareability values
enable the expected behaviour for the redistributors/ITSes
memory interconnect ports.

To enable non-coherent GIC designs, introduce the "dma-noncoherent"
device tree property to allow firmware to describe redistributors and
ITSes as non-coherent observers on the memory interconnect and use the
property to force the shareability attributes to be programmed into the
redistributors and ITSes registers through the GIC quirks mechanism.

[PATCH AUTOSEL 6.5 19/31] irqchip/riscv-intc: Mark all INTC nodes as initialized

[Sasha Levin]

From: Anup Patel <apatel@ventanamicro.com>

[ Upstream commit e13cd66bd821be417c498a34928652db4ac6b436 ]

The RISC-V INTC local interrupts are per-HART (or per-CPU) so we
create INTC IRQ domain only for the INTC node belonging to the boot
HART. This means only the boot HART INTC node will be marked as
initialized and other INTC nodes won't be marked which results
downstream interrupt controllers (such as PLIC, IMSIC and APLIC
direct-mode) not being probed due to missing device suppliers.

To address this issue, we mark all INTC node for which we don't
create IRQ domain as initialized.

[PATCH AUTOSEL 6.5 19/31] irqchip/riscv-intc: Mark all INTC nodes as initialized

[Sasha Levin]

From: Anup Patel <apatel@ventanamicro.com>

[ Upstream commit e13cd66bd821be417c498a34928652db4ac6b436 ]

The RISC-V INTC local interrupts are per-HART (or per-CPU) so we
create INTC IRQ domain only for the INTC node belonging to the boot
HART. This means only the boot HART INTC node will be marked as
initialized and other INTC nodes won't be marked which results
downstream interrupt controllers (such as PLIC, IMSIC and APLIC
direct-mode) not being probed due to missing device suppliers.

To address this issue, we mark all INTC node for which we don't
create IRQ domain as initialized.

[PATCH AUTOSEL 6.5 20/31] irqchip/stm32-exti: add missing DT IRQ flag translation

[Sasha Levin]

From: Ben Wolsieffer <ben.wolsieffer@hefring.com>

[ Upstream commit 8554cba1d6dbd3c74e0549e28ddbaccbb1d6b30a ]

The STM32F4/7 EXTI driver was missing the xlate callback, so IRQ trigger
flags specified in the device tree were being ignored. This was
preventing the RTC alarm interrupt from working, because it must be set
to trigger on the rising edge to function correctly.

The pm_runtime_enable will increase power disable depth. Thus
a pairing decrement is needed on the error handling path to
keep it balanced according to context.

[PATCH AUTOSEL 6.5 23/31] ACPI: resource: Add TongFang GM6BGEQ, GM6BG5Q and GM6BG0Q to irq1_edge_low_force_override[]

[Sasha Levin]

From: Hans de Goede <hdegoede@redhat.com>

[ Upstream commit f9b3ea02555e67e2e7bf95219953b88d122bd275 ]

The TongFang GM6BGEQ, GM6BG5Q and GM6BG0Q are 3 GPU variants of a TongFang
barebone design which is sold under various brand names.

The ACPI IRQ override for the keyboard IRQ must be used on these AMD Zen
laptops in order for the IRQ to work.

Adjust the pcspecialist_laptop[] DMI match table for this:

1. Drop the sys-vendor match from the existing PCSpecialist Elimina Pro 16
   entry for the GM6BGEQ (RTX3050 GPU) model so that it will also match
   the laptop when sold by other vendors such as hyperbook.pl.

2. Add board-name matches for the GM6BG5Q (RTX4050) and GM6B0Q (RTX4060)
   models.

Note the .ident values of the dmi_system_id structs are left unset
since these are not used.

[PATCH AUTOSEL 6.5 24/31] ata: pata_parport: add custom version of wait_after_reset

[Sasha Levin]

From: Ondrej Zary <linux@zary.sk>

[ Upstream commit f343e578fef99a69b3322aca38b94a6d8ded2ce7 ]

Some parallel adapters (e.g. EXP Computer MC-1285B EPP Cable) return
bogus values when there's no master device present. This can cause
reset to fail, preventing the lone slave device (such as EXP Computer
CD-865) from working.

Add custom version of wait_after_reset that ignores master failure when
a slave device is present. The custom version is also needed because
the generic ata_sff_wait_after_reset uses direct port I/O for slave
device detection.

[PATCH AUTOSEL 6.5 25/31] ata: pata_parport: fit3: implement IDE command set registers

[Sasha Levin]

From: Ondrej Zary <linux@zary.sk>

[ Upstream commit 0c1e81d0b5ebd5813536dd5fcf5966ad043f37dc ]

fit3 protocol driver does not support accessing IDE control registers
(device control/altstatus). The DOS driver does not use these registers
either (as observed from DOSEMU trace). But the HW seems to be capable
of accessing these registers - I simply tried bit 3 and it works!

The control register is required to properly reset ATAPI devices or
they will be detected only once (after a power cycle).

Tested with EXP Computer CD-865 with MC-1285B EPP cable and
TransDisk 3000.

[PATCH AUTOSEL 6.5 26/31] net: macsec: indicate next pn update when offloading

[Sasha Levin]

From: "Radu Pirea (NXP OSS)" <radu-nicolae.pirea@oss.nxp.com>

[ Upstream commit 0412cc846a1ef38697c3f321f9b174da91ecd3b5 ]

Indicate next PN update using update_pn flag in macsec_context.
Offloaded MACsec implementations does not know whether or not the
MACSEC_SA_ATTR_PN attribute was passed for an SA update and assume
that next PN should always updated, but this is not always true.

The PN can be reset to its initial value using the following command:
$ ip macsec set macsec0 tx sa 0 off #octeontx2-pf case

Or, the update PN command will succeed even if the driver does not support
PN updates.
$ ip macsec set macsec0 tx sa 0 pn 1 on #mscc phy driver case

Comparing the initial PN with the new PN value is not a solution. When
the user updates the PN using its initial value the command will
succeed, even if the driver does not support it. Like this:
$ ip macsec add macsec0 tx sa 0 pn 1 on key 00 \
ead3664f508eb06c40ac7104cdae4ce5
$ ip macsec set macsec0 tx sa 0 pn 1 on #mlx5 case

[PATCH AUTOSEL 6.5 28/31] media: i2c: ov8858: Don't set fwnode in the driver

[Sasha Levin]

From: Ondrej Jirman <megi@xff.cz>

[ Upstream commit c46f16f156ac58afcf4addc850bb5dfbca77b9fc ]

This makes the driver work with the new check in
v4l2_async_register_subdev() that was introduced recently in 6.6-rc1.
Without this change, probe fails with:

ov8858 1-0036: Detected OV8858 sensor, revision 0xb2
ov8858 1-0036: sub-device fwnode is an endpoint!
ov8858 1-0036: v4l2 async register subdev failed
ov8858: probe of 1-0036 failed with error -22

This also simplifies the driver a bit.

[PATCH AUTOSEL 6.5 29/31] Input: synaptics-rmi4 - handle reset delay when using SMBus trsnsport

[Sasha Levin]

From: Dmitry Torokhov <dmitry.torokhov@gmail.com>

[ Upstream commit 5030b2fe6aab37fe42d14f31842ea38be7c55c57 ]

Touch controllers need some time after receiving reset command for the
firmware to finish re-initializing and be ready to respond to commands
from the host. The driver already had handling for the post-reset delay
for I2C and SPI transports, this change adds the handling to
SMBus-connected devices.

SMBus devices are peculiar because they implement legacy PS/2
compatibility mode, so reset is actually issued by psmouse driver on the
associated serio port, after which the control is passed to the RMI4
driver with SMBus companion device.

Note that originally the delay was added to psmouse driver in
92e24e0e57f7 ("Input: psmouse - add delay when deactivating for SMBus
mode"), but that resulted in an unwanted delay in "fast" reconnect
handler for the serio port, so it was decided to revert the patch and
have the delay being handled in the RMI4 driver, similar to the other
transports.

[PATCH AUTOSEL 6.5 31/31] Input: powermate - fix use-after-free in powermate_config_complete

[Sasha Levin]

From: Javier Carrasco <javier.carrasco.cruz@gmail.com>

[ Upstream commit 5c15c60e7be615f05a45cd905093a54b11f461bc ]

syzbot has found a use-after-free bug [1] in the powermate driver. This
happens when the device is disconnected, which leads to a memory free from
the powermate_device struct.  When an asynchronous control message
completes after the kfree and its callback is invoked, the lock does not
exist anymore and hence the bug.

Use usb_kill_urb() on pm->config to cancel any in-progress requests upon
device disconnection.
