platform-drivers-x86 for v5.14-1

Browse source 
Highlights:
  - New think-lmi driver adding support for changing 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
 
 Note this also contains merges of the following immutable branches/tags
 shared with other subsystems:
  - platform-drivers-x86-goodix-v5.14-1
  - intel-gpio-v5.14-1
  - linux-pm/acpi-scan
  - devm-helpers-v5.14-1
