Merge tag 'pm-6.5-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management fixes from Rafael Wysocki:
 "These fix an amd-pstate cpufreq driver issues and recently introduced
  hibernation-related breakage.

  Specifics:

   - Make amd-pstate use device_attributes as expected by the CPU root
     kobject (Thomas Weißschuh)

   - Restore the previous behavior of resume_store() when hibernation is
     not available which is to return the full number of bytes that were
     to be written by user space (Vlastimil Babka)"
