Merge tag 'platform-drivers-x86-v5.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86

Pull x86 platform driver updates from Hans de Goede:
 "Highlights:

   - Microsoft Surface devices System Aggregator Module support

   - SW_TABLET_MODE reporting improvements

   - thinkpad_acpi keyboard language setting support

   - platform / DPTF profile settings support:

      - Base / userspace API parts merged from Rafael's acpi-platform
        branch

      - thinkpad_acpi and ideapad-laptop support through pdx86

   - Remove support for some obsolete Intel MID platforms through
     merging of the shared intel-mid-removal branch

   - Big cleanup of the ideapad-laptop driver

   - Misc other fixes / new hw support / quirks"
