Merge tag 'pm-5.16-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management fixes from Rafael Wysocki:
"These address three issues in the intel_pstate driver and fix two
problems related to hibernation.
Specifics:
- Make intel_pstate work correctly on Ice Lake server systems with
out-of-band performance control enabled (Adamos Ttofari).
- Fix EPP handling in intel_pstate during CPU offline and online in
the active mode (Rafael Wysocki).
- Make intel_pstate support ITMT on asymmetric systems with
overclocking enabled (Srinivas Pandruvada).
- Fix hibernation image saving when using the user space interface
based on the snapshot special device file (Evan Green).
- Make the hibernation code release the snapshot block device using
the same mode that was used when acquiring it (Thomas Zeitlhofer)"
