Merge tag 'acpi-5.16-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull more ACPI updates from Rafael Wysocki:
"These add support for a new ACPI device configuration object called
_DSC, fix some issues including one recent regression, add two new
items to quirk lists and clean up assorted pieces of code.
Specifics:
- Add support for new ACPI device configuration object called _DSC
("Deepest State for Configuration") to allow certain devices to be
probed without changing their power states, document it and make
two drivers use it (Sakari Ailus, Rajmohan Mani).
- Fix device wakeup power reference counting broken recently by
mistake (Rafael Wysocki).
- Drop unused symbol and macros depending on it from acgcc.h (Rafael
Wysocki).
- Add HP ZHAN 66 Pro to the "no EC wakeup" quirk list (Binbin Zhou).
- Add Xiaomi Mi Pad 2 to the backlight quirk list and drop an unused
piece of data from all of the list entries (Hans de Goede).
- Fix register read accesses handling in the Intel PMIC operation
region driver (Hans de Goede).
- Clean up static variables initialization in the EC driver
(wangzhitong)"
