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"
