platform/chrome: chromeos_acpi: print hex string for ACPI_TYPE_BUFFER

2023-09-13T07:53:55+00:00

commit 0820debb7d489e9eb1f68b7bb69e6ae210699b3f upstream.

`element->buffer.pointer` should be binary blob.  `%s` doesn't work
perfect for them.

Print hex string for ACPI_TYPE_BUFFER.  Also update the documentation
to reflect this.

platform/x86/amd/pmf: Fix a missing cleanup path

2023-09-13T07:53:45+00:00

[ Upstream commit 4dbd6e61adc7e52dd1c9165f0ccaa90806611e40 ]

On systems that support slider notifications but don't otherwise support
granular slider the SPS cleanup path doesn't run.

This means that loading/unloading/loading leads to failures because
the sysfs files don't get setup properly when reloaded.

Add the missing cleanup path.

platform/x86: dell-sysman: Fix reference leak

2023-09-13T07:53:40+00:00

[ Upstream commit 7295a996fdab7bf83dc3d4078fa8b139b8e0a1bf ]

If a duplicate attribute is found using kset_find_obj(),
a reference to that attribute is returned. This means
that we need to dispose it accordingly. Use kobject_put()
to dispose the duplicate attribute in such a case.

Compile-tested only.

platform/x86: lenovo-ymc: Only bind on machines with a convertible DMI chassis-type

2023-08-13T12:50:25+00:00

The lenovo-ymc driver is causing the keyboard + touchpad to stop working
on some regular laptop models such as the Lenovo ThinkBook 13s G2 ITL 20V9.

The problem is that there are YMC WMI GUID methods in the ACPI tables
of these laptops, despite them not being Yogas and lenovo-ymc loading
causes libinput to see a SW_TABLET_MODE switch with state 1.

This in turn causes libinput to ignore events from the builtin keyboard
and touchpad, since it filters those out for a Yoga in tablet mode.

Similar issues with false-positive SW_TABLET_MODE=1 reporting have
been seen with the intel-hid driver.

Copy the intel-hid driver approach to fix this and only bind to the WMI
device on machines where the DMI chassis-type indicates the machine
is a convertible.

Add a 'force' module parameter to allow overriding the chassis-type check
so that users can easily test if the YMC interface works on models which
report an unexpected chassis-type.
