returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

models only
When support for instantiating an i2c-client for the fuel-gauge was
added for the Windows based Yoga Book YB1-X91F/L models, the assumption
was made that this would apply to the Android based YB1-X90F/L models too.
But these have a completely different BIOS with completely different DMI
strings. Update the existing YB1-X91 support to reflect that it only
applies to the YB1-X91F/L models.

Pro YT3-X90F
The YT3 uses an TI LP8557 LED backlight controller, the LP8557's PWM input
is connected to a PWM output coming from the LCD panel's controller.
The Android kernel has a hack in the i915 driver to write the non-standard
DSI reg 0x51 with the desired level to set the duty-cycle of the LCD's PWM.
To avoid having to have a similar hack in the mainline kernel program
instantiate an i2c-client for the LP8557 with platform-data to have
the LP8557 to directly set the level (ignoring its PWM input), this allows
backlight brightness control through a backlight device registered by
the lp855x_bl driver.

C1010
The Peaq C1010 tablet has a special "Dolby" button. This button has
a WMI interface, but this is broken in several ways:
1. It only supports polling
2. The value read on polling goes from 0 -> 1 for one poll on both edges
of the button, with no way to tell which edge causes the poll to
return 1.
3. It uses a non unique GUID (it uses the Microsoft docs WMI example GUID).
There currently is a WMI driver for this, but it uses several kludges
to work around these issues and is not entirely reliable due to 2.
Replace the unreliable WMI driver by using the x86-android-tablets code
to instantiate a gpio_keys device for this.

directly thru "make *config", so drivers should select it instead of

Consistently using "select" or "depends on" can also help reduce

drivers/platform/x86/intel/tpmi.c:253 tpmi_create_device()
warn: 'feature_vsec_dev' was already freed.
If there is some error, feature_vsec_dev memory is freed as part
of resource managed call intel_vsec_add_aux(). So, additional
kfree() call is not required.
Reordered res allocation and feature_vsec_dev, so that on error
only res is freed.

A new command CONFIG_TDP_GET_RATIO_INFO is added, with sub command type
of 0x0C. The previous range of valid sub commands was from 0x00 to 0x0B.
Change the valid range from 0x00 to 0x0C.

After using the built-in UEFI hardware diagnostics to compare
the measured battery temperature, i noticed that the temperature
is actually expressed in tenth degree kelvin, similar to the
SBS-Data standard. For example, a value of 2992 is displayed as
26 degrees celsius.
Fix the scaling so that the correct values are being displayed.
Tested on a Dell Inspiron 3505.

If one or both sensor buffers could not be initialized, either
due to missing hardware support or due to some error during probing,
the resume handler will encounter undefined behaviour when
attempting to lock buffers then protected by an uninitialized or
destroyed mutex.
Fix this by introducing a "active" flag which is set during probe,
and only invalidate buffers which where flaged as "active".

The amd_pmc_write_stb() function was previously hidden in an
ifdef to avoid a warning when CONFIG_SUSPEND is disabled, but
now there is an additional caller:

drivers/platform/x86/amd/pmc.c:256:8: error: implicit declaration of function 'amd_pmc_write_stb'; did you mean 'amd_pmc_read_stb'? [-Werror=implicit-function-declaration]

There is now an easier way to handle this using DEFINE_SIMPLE_DEV_PM_OPS()
to replace all the #ifdefs, letting gcc drop any of the unused functions
silently.

The thermal zone parameter specifies the bang-bang governor.
The Kconfig selects the bang-bang governor. So it is pointless to test
if the governor was set for the thermal zone assuming it may not have
been compiled-in.
Remove the test and prevent another access into the thermal internals.

The thermal zone device structure is in the process of being private
to the thermal framework core code. This driver is directly accessing
and changing the monitoring polling rate.
After discussing with the maintainers of this driver, having the
polling interval at module loading time is enough for their purpose.
Change the code to take into account the interval when the module is
loaded but restrict the permissions so the value can not be changed
afterwards.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core updates from Greg KH:
"Here is the large set of driver core changes for 6.3-rc1.
There's a lot of changes this development cycle, most of the work
falls into two different categories:
- fw_devlink fixes and updates. This has gone through numerous review
cycles and lots of review and testing by lots of different devices.
Hopefully all should be good now, and Saravana will be keeping a
watch for any potential regression on odd embedded systems.
- driver core changes to work to make struct bus_type able to be
moved into read-only memory (i.e. const) The recent work with Rust
has pointed out a number of areas in the driver core where we are
passing around and working with structures that really do not have
to be dynamic at all, and they should be able to be read-only
making things safer overall. This is the contuation of that work
(started last release with kobject changes) in moving struct
bus_type to be constant. We didn't quite make it for this release,
but the remaining patches will be finished up for the release after
this one, but the groundwork has been laid for this effort.
Other than that we have in here:
- debugfs memory leak fixes in some subsystems
- error path cleanups and fixes for some never-able-to-be-hit
codepaths.
- cacheinfo rework and fixes
- Other tiny fixes, full details are in the shortlog
All of these have been in linux-next for a while with no reported
problems"

that there's a pending report that has a fix that is queued up - Linus ]
