[PATCH AUTOSEL 5.17 09/23] platform/x86: thinkpad_acpi: Convert btusb DMI list to quirks

[Sasha Levin]

From: Mario Limonciello <mario.limonciello@amd.com>

[ Upstream commit c25d7f32e3e209462cd82e6e93e66b72dbb2308f ]

DMI matching in thinkpad_acpi happens local to a function meaning
quirks can only match that function.

Future changes to thinkpad_acpi may need to quirk other code, so
change this to use a quirk infrastructure.

[PATCH AUTOSEL 5.17 10/23] platform/x86: thinkpad_acpi: Correct dual fan probe

[Sasha Levin]

From: Mark Pearson <markpearson@lenovo.com>

[ Upstream commit aa2fef6f40e6ccc22e932b36898f260f0e5a021a ]

There was an issue with the dual fan probe whereby the probe was
failing as it assuming that second_fan support was not available.

Corrected the logic so the probe works correctly. Cleaned up so
quirks only used if 2nd fan not detected.

Tested on X1 Carbon 10 (2 fans), X1 Carbon 9 (2 fans) and T490 (1 fan)

The probe function, pmt_telem_probe(), adds an entry for devices even if
they have not been initialized.  This results in the array of initialized
devices containing both initialized and uninitialized entries.  This
causes a panic in the remove function, pmt_telem_remove() which expects
the array to only contain initialized entries.

Only use an entry when a device is initialized.

[PATCH AUTOSEL 5.17 12/23] platform/surface: gpe: Add support for Surface Pro 8

[Sasha Levin]

From: Maximilian Luz <luzmaximilian@gmail.com>

[ Upstream commit ed13d4ac57474d959c40fd05d8860e2b1607becb ]

The new Surface Pro 8 uses GPEs for lid events as well. Add an entry for
that so that the lid can be used to wake the device. Note that this is a
device with a keyboard type-cover, where this acts as the "lid".
