Merge branches 'acpi-video', 'acpi-resource', 'acpi-pad' and 'acpi-misc'

Merge ACPI backlight (video) driver update, ACPI resource management
updates, an ACPI processor aggregator device (PAD) driver fix, and
miscellaneous ACPI updates for 6.12-rc1:

 - Add force_vendor quirk for Panasonic Toughbook CF-18 in the ACPI
   backlight driver (Hans de Goede).

 - Make the DMI checks related to backlight handling on Lenovo Yoga
   Tab 3 X90F less strict (Hans de Goede).

 - Enforce native backlight handling on Apple MacbookPro9,2 (Esther
   Shimanovich).

 - Add IRQ override quirks for Asus Vivobook Go E1404GAB and MECHREV
   GM7XG0M, and refine the TongFang GMxXGxx quirk (Li Chen, Tamim Khan,
   Werner Sembach).

 - Fix crash in exit_round_robin() in the ACPI processor aggregator
   device (PAD) driver (Seiji Nishikawa).

 - Define and use symbols for device and class name lengths in the ACPI
   bus type code and make the code use strscpy() instead of strcpy() in
   several places (Muhammad Qasim Abdul Majeed).

* acpi-video:
  ACPI: video: Add force_vendor quirk for Panasonic Toughbook CF-18
  ACPI: x86: Make Lenovo Yoga Tab 3 X90F DMI match less strict
  ACPI: video: Make Lenovo Yoga Tab 3 X90F DMI match less strict

* acpi-resource:
  ACPI: resource: Add another DMI match for the TongFang GMxXGxx
  ACPI: resource: Skip IRQ override on Asus Vivobook Go E1404GAB
  ACPI: resource: Do IRQ override on MECHREV GM7XG0M

* acpi-pad:
  ACPI: PAD: fix crash in exit_round_robin()

* acpi-misc:
  ACPI: button: Use strscpy() instead of strcpy()
  ACPI: bus: Define and use symbols for device and class name lengths
  ACPI: battery : Use strscpy() instead of strcpy()
  ACPI: acpi_processor: Use strscpy instead() of strcpy()
  ACPI: PAD: Use strscpy() instead of strcpy()
