Merge branches 'acpi-battery', 'acpi-video' and 'acpi-misc'

Merge ACPI battery and backlight driver update and miscellaneous
cleanup for 5.19-rc1:

 - Make the ACPI battery driver show the "not-charging" status by
   default unless "charging" or "full" is directly indicated (Werner
   Sembach).

 - Improve the PM notifier in the ACPI backlight driver (Zhang Rui).

 - Clean up some white space in the ACPI code (Ian Cowan).

* acpi-battery:
  ACPI: battery: Make "not-charging" the default on no charging or full info

* acpi-video:
  ACPI: video: improve PM notifer callback

* acpi-misc:
  ACPI: clean up white space in a few places for consistency
