Merge tag 'acpi-6.2-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI fixes from Rafael Wysocki:
"These update the ACPICA entry in MAINTAINERS, add a backlight handling
quirk and fix the ACPI PRM (platform runtime) mechanism support.

Specifics:

- Update the ACPICA development list address in MAINTAINERS to the
new one that does not bounce (Rafael Wysocki)

- Check whether EFI runtime is available when registering the ACPI
PRM address space handler and when running it (Ard Biesheuvel)

- Add backlight=native DMI quirk for Acer Aspire 4810T to the ACPI
video driver (Hans de Goede)"
