Merge tag 'acpi-5.19-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm 

Pull more ACPI updates from Rafael Wysocki:
 "These add some new device IDs, update a few drivers (processor,
  battery, backlight) and clean up code in a few places.

  Specifics:

   - Add Meteor Lake ACPI IDs for DPTF devices (Sumeet Pawnikar)

   - Rearrange find_child_checks() to simplify code (Rafael Wysocki)

   - Use memremap() to map the UCSI mailbox that is always in main
     memory and drop acpi_release_memory() that has no more users
     (Heikki Krogerus, Dan Carpenter)

   - Make max_cstate/nocst/bm_check_disable processor module parameters
     visible in sysfs (Yajun Deng)

   - Fix typo in the CPPC driver (Julia Lawall)

   - 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)"
