Merge tag 'acpi-5.14-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull more ACPI updates from Rafael Wysocki:
"These include fixes of the recently introduced support for the
Platform Runtime Mechanism (PRM) feature, a new backlight quirk, a
suspend-to-idle wakeup fix for non-Intel platforms and a fix for the
AMBA bus resource list in /proc/iomem.
Specifics:
- Fix up the recently added Platform Runtime Mechanism (PRM) support
by correnting a couple of implementation mistakes in it and adding
a Kconfig help text to describe it (Aubrey Li, Rafael Wysocki).
- Add backlight quirk for Dell Vostro 3350 (Hans de Goede).
- Avoid spurious wakeups from suspend-to-idle on non-Intel platforms
by restricting special EC GPE handling to the Intel ones (Mario
Limonciello).
- Modify the AMBA bus support in ACPI to avoid adding using resource
names in /proc/iomem (Liguang Zhang)"
