Merge tag 'platform-drivers-x86-v5.14-1' of git://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86

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

   - New think-lmi driver adding support for changing Lenovo Thinkpad
     BIOS settings from within Linux using the standard firmware-
     attributes class sysfs API

   - MS Surface aggregator-cdev now also supports forwarding events to
     user-space (for debugging / new driver development purposes only)

   - New intel_skl_int3472 driver this provides the necessary glue to
     translate ACPI table information to GPIOs, regulators, etc. for
     camera sensors on Intel devices with IPU3 attached MIPI cameras

   - A whole bunch of other fixes + device-specific quirk additions

   - New devm_work_autocancel() devm-helpers.h function"
