[PATCH AUTOSEL 5.4 003/266] ASoC: tegra: tegra_wm8903: Support nvidia, headset property

[Sasha Levin]

From: Dmitry Osipenko <digetx@gmail.com>

[ Upstream commit 3ef9d5073b552d56bd6daf2af1e89b7e8d4df183 ]

The microphone-jack state needs to be masked in a case of a 4-pin jack
when microphone and ground pins are shorted. Presence of nvidia,headset
tells that WM8903 CODEC driver should mask microphone's status if short
circuit is detected, i.e headphones are inserted.

[PATCH AUTOSEL 5.4 013/266] ASoC: davinci-mcasp: Fix dma_chan refcnt leak when getting dma type

[Sasha Levin]

From: Xiyu Yang <xiyuyang19@fudan.edu.cn>

[ Upstream commit a697ae6ea56e23397341b027098c1b11d9ab13da ]

davinci_mcasp_get_dma_type() invokes dma_request_chan(), which returns a
reference of the specified dma_chan object to "chan" with increased
refcnt.

When davinci_mcasp_get_dma_type() returns, local variable "chan" becomes
invalid, so the refcount should be decreased to keep refcount balanced.

The reference counting issue happens in one exception handling path of
davinci_mcasp_get_dma_type(). When chan device is NULL, the function
forgets to decrease the refcnt increased by dma_request_chan(), causing
a refcnt leak.

Fix this issue by calling dma_release_channel() when chan device is
NULL.

[PATCH AUTOSEL 5.4 019/266] ALSA: hda/realtek - Introduce polarity for micmute LED GPIO

[Sasha Levin]

From: Kai-Heng Feng <kai.heng.feng@canonical.com>

[ Upstream commit dbd13179780555ecd3c992dea1222ca31920e892 ]

Currently mute LED and micmute LED share the same GPIO polarity.

So split the polarity for mute and micmute, in case they have different
polarities.

[PATCH AUTOSEL 5.4 041/266] ASoC: SOF: Do nothing when DSP PM callbacks are not set

[Sasha Levin]

From: Daniel Baluta <daniel.baluta@nxp.com>

[ Upstream commit c26fde3b15ed41f5f452f1da727795f787833287 ]

This provides a better separation between runtime and PM sleep
callbacks.

Only do nothing if given runtime flag is set and calback is not set.

With the current implementation, if PM sleep callback is set but runtime
callback is not set then at runtime resume we reload the firmware even
if we do not support runtime resume callback.

[PATCH AUTOSEL 5.4 101/266] ALSA: usb-audio: Improve frames size computation

[Sasha Levin]

From: Alexander Tsoy <alexander@tsoy.me>

[ Upstream commit f0bd62b64016508938df9babe47f65c2c727d25c ]

For computation of the the next frame size current value of fs/fps and
accumulated fractional parts of fs/fps are used, where values are stored
in Q16.16 format. This is quite natural for computing frame size for
asynchronous endpoints driven by explicit feedback, since in this case
fs/fps is a value provided by the feedback endpoint and it's already in
the Q format. If an error is accumulated over time, the device can
adjust fs/fps value to prevent buffer overruns/underruns.

But for synchronous endpoints the accuracy provided by these computations
is not enough. Due to accumulated error the driver periodically produces
frames with incorrect size (+/- 1 audio sample).

This patch fixes this issue by implementing a different algorithm for
frame size computation. It is based on accumulating of the remainders
from division fs/fps and it doesn't accumulate errors over time. This
new method is enabled for synchronous and adaptive playback endpoints.

[PATCH AUTOSEL 5.4 102/266] ALSA: usb-audio: Fix racy list management in output queue

[Sasha Levin]

From: Takashi Iwai <tiwai@suse.de>

[ Upstream commit 5b6cc38f3f3f37109ce72b60bda215a5f6892c0b ]

The linked list entry from FIFO is peeked at
queue_pending_output_urbs() but the actual element pop-out is
performed outside the spinlock, and it's potentially racy.

Do delete the link at the right place inside the spinlock.

[PATCH AUTOSEL 5.4 113/266] ASoC: max98373: reorder max98373_reset() in resume

[Sasha Levin]

From: Yong Zhi <yong.zhi@intel.com>

[ Upstream commit 1a446873d7dd3a450f685928ce7f1907bde4583d ]

During S3 test, the following error was observed:

[ 726.174237] i2c_designware i2c_designware.0: platform_pm_resume+0x0/0x3d returned 0 after 0 usecs
[ 726.184187] max98373 i2c-MX98373:00: calling max98373_resume+0x0/0x30 [snd_soc_max98373] @ 12698, parent: i2c-11
[ 726.195589] max98373 i2c-MX98373:00: Reset command failed. (ret:-16)

When calling regmap_update_bits(), since map->reg_update_bits is NULL,
_regmap_read() is entered with the following logic:

	if (!map->cache_bypass) {
		ret = regcache_read(map, reg, val);
		if (ret == 0)
			return 0;
	}

	if (map->cache_only)
		return -EBUSY;

regcache_read() hits -EINVAL because MAX98373_R2000_SW_RESET is volatile,
as map->cache_only is set by codec suspend, thus -EBUSY is returned.
Fix by moving max98373_reset() after cache_only set to false in max98373_resume().

lead to errors in pcm data.
This patch adds overflow and underflow interrupt support for SSI BUSIF buffer.

[PATCH AUTOSEL 5.4 135/266] ASoC: ux500: mop500: Fix some refcounted resources issues

[Sasha Levin]

From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

[ Upstream commit 4e8748fcaeec073e3ba794871ce86c545e4f961f ]

There are 2 issues here:
   - if one of the 'of_parse_phandle' fails, calling 'mop500_of_node_put()'
     is a no-op because the 'mop500_dai_links' structure has not been
     initialized yet, so the referenced are not decremented
   - The reference stored in 'mop500_dai_links[i].codecs' is refcounted
     only once in the probe and must be decremented only once.

[PATCH AUTOSEL 5.4 136/266] ASoC: ti: omap-mcbsp: Fix an error handling path in 'asoc_mcbsp_probe()'

[Sasha Levin]

From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

[ Upstream commit 03990fd58d2b7c8f7d53e514ba9b8749fac260f9 ]

If an error occurs after the call to 'omap_mcbsp_init()', the reference to
'mcbsp->fclk' must be decremented, as already done in the remove function.

This can be achieved easily by using the devm_ variant of 'clk_get()'
when the reference is taken in 'omap_mcbsp_init()'

This fixes the leak in the probe and has the side effect to simplify both
the error handling path of 'omap_mcbsp_init()' and the remove function.

[PATCH AUTOSEL 5.4 145/266] ALSA: usb-audio: Add duplex sound support for USB devices using implicit feedback

[Sasha Levin]

From: Erwin Burema <e.burema@gmail.com>

[ Upstream commit 10ce77e4817fef99e1166be7e6685a80c63bf77f ]

For USB sound devices using implicit feedback the endpoint used for
this feedback should be able to be opened twice, once for required
feedback and second time for audio data. This way these devices can be
put in duplex audio mode. Since this only works if the settings of the
endpoint don't change a check is included for this.

This fixes bug 207023 ("MOTU M2 regression on duplex audio") and
should also fix bug 103751 ("M-Audio Fast Track Ultra usb audio device
will not operate full-duplex")

[PATCH AUTOSEL 5.4 157/266] ASoC: Intel: bytcr_rt5640: Add quirk for Toshiba Encore WT8-A tablet

[Sasha Levin]

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

[ Upstream commit 0e0e10fde0e9808d1991268f5dca69fb36c025f7 ]

The Toshiba Encore WT8-A tablet almost fully works with the default
settings for non-CR Bay Trail devices. The only problem is that its
jack-detect switch is not inverted (it is active high instead of
the normal active low).

Add a quirk for this model using the default settings +
BYT_RT5640_JD_NOT_INV.

[PATCH AUTOSEL 5.4 209/266] ASoC: fsl_asrc_dma: Fix dma_chan leak when config DMA channel failed

[Sasha Levin]

From: Xiyu Yang <xiyuyang19@fudan.edu.cn>

[ Upstream commit 36124fb19f1ae68a500cd76a76d40c6e81bee346 ]

fsl_asrc_dma_hw_params() invokes dma_request_channel() or
fsl_asrc_get_dma_channel(), which returns a reference of the specified
dma_chan object to "pair->dma_chan[dir]" with increased refcnt.

The reference counting issue happens in one exception handling path of
fsl_asrc_dma_hw_params(). When config DMA channel failed for Back-End,
the function forgets to decrease the refcnt increased by
dma_request_channel() or fsl_asrc_get_dma_channel(), causing a refcnt
leak.

Fix this issue by calling dma_release_channel() when config DMA channel
failed.

[PATCH AUTOSEL 5.4 250/266] ASoC: core: only convert non DPCM link to DPCM link

[Sasha Levin]

From: Bard Liao <yung-chuan.liao@linux.intel.com>

[ Upstream commit 607fa205a7e4dfad28b8a67ab1c985756ddbccb0 ]

Additional checks for valid DAIs expose a corner case, where existing
BE dailinks get modified, e.g. HDMI links are tagged with
dpcm_capture=1 even if the DAIs are for playback.

This patch makes those changes conditional and flags configuration
issues when a BE dailink is has no_pcm=0 but dpcm_playback or
dpcm_capture=1 (which makes no sense).

As discussed on the alsa-devel mailing list, there are redundant flags
for dpcm_playback, dpcm_capture, playback_only, capture_only. This
will have to be cleaned-up in a future update. For now only correct
and flag problematic configurations.

[ Upstream commit 79d4f823a06796656289f97b922493da5690e46c ]

The Asus T101HA uses the default jack-detect mode 3, but instead of
using an analog microphone it is using a DMIC on dmic-data-pin 1,
like the Asus T100HA. Note unlike the T100HA its jack-detect is not
inverted.
