Subject: [GIT PULL] More ACPI updates for v5.16-rc1

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 acpi-5.16-rc1-2

with top-most commit 314c6e2b4545efd5b88988f2308e90eda6a4bcf1

 Merge branches 'acpica', 'acpi-ec', 'acpi-pmic' and 'acpi-video'

on top of commit c0d6586afa3546a3d148cf4b9d9a407b4f79d0bb

 Merge tag 'acpi-5.16-rc1' of
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

to receive more ACPI updates for 5.16-rc1.

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
   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).

Thanks!
