  two bugs in laptop platform driver"

* tag 'loongarch-fixes-6.1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/chenhuacai/linux-loongson:

platform/loongarch: laptop: Fix possible UAF and simplify generic_acpi_laptop_init()

2022-10-29T08:29:31+00:00

Currently the return value of 'sub_driver->init' is not checked. If
sparse_keymap_setup() called in the init function fails, 'generic_
inputdev' is freed, then it will lead a UAF when using it in generic_
acpi_laptop_init(). Fix it by checking the return value and setting
generic_inputdev to NULL after free, so as to avoid double free it.

The error code in generic_subdriver_init() is always negative, so the
return of generic_subdriver_init() can be simplified.

platform/loongarch: laptop: Adjust resume order for loongson_hotkey_resume()

2022-10-29T08:29:31+00:00

Some laptops don't support SW_LID, but still have backlight control,
move backlight resuming before SW_LID event handling so as to avoid
backlight mistake due to early return.

platform/x86/intel: pmc/core: Add Raptor Lake support to pmc core driver

2022-10-24T09:39:27+00:00

Add Raptor Lake client parts (both RPL and RPL_S) support to pmc core
driver. Raptor Lake client parts reuse all the Alder Lake PCH IPs.

platform/x86/amd: pmc: Read SMU version during suspend on Cezanne systems

2022-10-24T09:27:35+00:00

commit b0c07116c894 ("platform/x86: amd-pmc: Avoid reading SMU version at
probe time") adjusted the behavior for amd-pmc to avoid reading the SMU
version at startup but rather on first use to improve boot time.

However the SMU version is also used to decide whether to place a timer
based wakeup in the OS_HINT message. If the idlemask hasn't been read
before this message was sent then the SMU version will not have been
cached.

Ensure the SMU version has been read before deciding whether or not to
run this codepath.

platform/x86: thinkpad_acpi: Fix reporting a non present second fan on some models

2022-10-24T09:24:08+00:00

thinkpad_acpi was reporting 2 fans on a ThinkPad T14s gen 1, even though
the laptop has only 1 fan.

The second, not present fan always reads 65535 (-1 in 16 bit signed),
ignore fans which report 65535 to avoid reporting the non present fan.

Pull interrupt updates from Thomas Gleixner:
 "Core code:

   - Provide a generic wrapper which can be utilized in drivers to
     handle the problem of force threaded demultiplex interrupts on RT
     enabled kernels. This avoids conditionals and horrible quirks in
     drivers all over the place

   - Fix up affected pinctrl and GPIO drivers to make them cleanly RT
     safe

  Interrupt drivers:

   - A new driver for the FSL MU platform specific MSI implementation

   - Make irqchip_init() available for pure ACPI based systems

   - Provide a functional DT binding for the Realtek RTL interrupt chip

   - The usual DT updates and small code improvements all over the
