[PATCH AUTOSEL 5.5 014/106] power: supply: bq27xxx_battery: Silence deferred-probe error

[Sasha Levin]

From: Dmitry Osipenko <digetx@gmail.com>

[ Upstream commit 583b53ece0b0268c542a1eafadb62e3d4b0aab8c ]

The driver fails to probe with -EPROBE_DEFER if battery's power supply
(charger driver) isn't ready yet and this results in a bit noisy error
message in KMSG during kernel's boot up. Let's silence the harmless
error message.

[PATCH AUTOSEL 5.5 033/106] drivers: thermal: tsens: Release device in success path

[Sasha Levin]

From: Amit Kucheria <amit.kucheria@linaro.org>

[ Upstream commit f22a3bf0d2225fba438c46a25d3ab8823585a5e0 ]

We don't currently call put_device in case of successfully initialising
the device. So we hold the reference and keep the device pinned forever.

Allow control to fall through so we can use same code for success and
error paths to put_device.

As a part of this fixup, change devm_ioremap_resource to act on the same
device pointer as that used to allocate regmap memory. That ensures that
we are free to release op->dev after examining its resources.

[PATCH AUTOSEL 5.5 041/106] thermal/drivers/cpufreq_cooling: Fix return of cpufreq_set_cur_state

[Sasha Levin]

From: Willy Wolff <willy.mh.wolff.ml@gmail.com>

[ Upstream commit ff44f672d74178b3be19d41a169b98b3e391d4ce ]

When setting the cooling device current state from userspace via sysfs,
the operation fails by returning an -EINVAL.

It appears the recent changes with the per-policy frequency QoS
introduced a regression as reported by:

 https://lkml.org/lkml/2020/3/20/599

The function freq_qos_update_request returns 0 or 1 describing update
effectiveness, and a negative error code on failure. However,
cpufreq_set_cur_state returns 0 on success or an error code otherwise.

Consider the QoS update as successful if the function does not return
an error.

[PATCH AUTOSEL 5.5 054/106] dt-bindings: thermal: tsens: Fix nvmem-cell-names schema

[Sasha Levin]

From: Rob Herring <robh@kernel.org>

[ Upstream commit b9589def9f9af93d9d4c5969c9a6c166f070e36e ]

There's a typo 'nvmem-cells-names' in the schema which means the correct
'nvmem-cell-names' in the examples are not checked. The possible values
are wrong too both in that the 2nd entry is not specified correctly and the
values are just wrong based on the dts files in the kernel.

[PATCH AUTOSEL 5.5 072/106] drm/nouveau: workaround runpm fail by disabling PCI power management on certain intel bridges

[Sasha Levin]

From: Karol Herbst <kherbst@redhat.com>

[ Upstream commit 434fdb51513bf3057ac144d152e6f2f2b509e857 ]

Fixes the infamous 'runtime PM' bug many users are facing on Laptops with
Nvidia Pascal GPUs by skipping said PCI power state changes on the GPU.

Depending on the used kernel there might be messages like those in demsg:

"nouveau 0000:01:00.0: Refused to change power state, currently in D3"
"nouveau 0000:01:00.0: can't change power state from D3cold to D0 (config
space inaccessible)"
followed by backtraces of kernel crashes or timeouts within nouveau.

It's still unkown why this issue exists, but this is a reliable workaround
and solves a very annoying issue for user having to choose between a
crashing kernel or higher power consumption of their Laptops.

[PATCH AUTOSEL 5.5 075/106] x86: ACPI: fix CPU hotplug deadlock

[Sasha Levin]

From: Qian Cai <cai@lca.pw>

[ Upstream commit 696ac2e3bf267f5a2b2ed7d34e64131f2287d0ad ]

Similar to commit 0266d81e9bf5 ("acpi/processor: Prevent cpu hotplug
deadlock") except this is for acpi_processor_ffh_cstate_probe():

"The problem is that the work is scheduled on the current CPU from the
hotplug thread associated with that CPU.

It's not required to invoke these functions via the workqueue because
the hotplug thread runs on the target CPU already.

Check whether current is a per cpu thread pinned on the target CPU and
invoke the function directly to avoid the workqueue."

[PATCH AUTOSEL 5.5 100/106] power: supply: axp288_fuel_gauge: Broaden vendor check for Intel Compute Sticks.

[Sasha Levin]

From: Jeffery Miller <jmiller@neverware.com>

[ Upstream commit e42fe5b29ac07210297e75f36deefe54edbdbf80 ]

The Intel Compute Stick `STK1A32SC` can have a system vendor of
"Intel(R) Client Systems".
Broaden the Intel Compute Stick DMI checks so that they match "Intel
Corporation" as well as "Intel(R) Client Systems".

This fixes an issue where the STK1A32SC compute sticks were still
exposing a battery with the existing blacklist entry.
