Merge tag 'acpi-5.17-rc1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull extra ACPI updates from Rafael Wysocki:
 "These fix and clean up the ACPI CPPC driver on top of the recent
  changes in it merged previously and add some new device IDs to the
  ACPI DPTF driver.

  Specifics:

   - Fix a recently introduced endianness-related issue in the ACPI CPPC
     library and clean it up on top of that (Rafael Wysocki)

   - Add new device IDs for the Raptor Lake SoC to the ACPI DPTF driver
     (Srinivas Pandruvada)"

* tag 'acpi-5.17-rc1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
  ACPI: DPTF: Support Raptor Lake
  ACPI: CPPC: Drop redundant local variable from cpc_read()
  ACPI: CPPC: Fix up I/O port access in cpc_read()
