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

   - Fix brightness key events getting reported twice on some Dells.
     Regression caused by recent Panasonic hotkey fixes

   - Fix poweroff no longer working on some devices regression caused
     by recent poweroff handler rework

   - Mark new (in 5.19) Intel IFS driver as broken, because of some
     issues surrounding the userspace (sysfs) API which need to be
     cleared up

   - Some hardware-id / quirk additions"
