Pull x86 platform driver fixes from Hans de Goede:

- 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"
