Merge tag 'pm-5.7-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management fixes from Rafael Wysocki:
- prevent the intel_pstate driver from printing excessive diagnostic
messages in some cases (Chris Wilson)
- make the hibernation restore kernel freeze kernel threads as well as
user space tasks (Dexuan Cui)
- fix the ACPI device PM disagnostic messages to include the correct
power state name (Kai-Heng Feng).
* tag 'pm-5.7-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
PM: ACPI: Output correct message on target power state
PM: hibernate: Freeze kernel threads in software_resume()
cpufreq: intel_pstate: Only mention the BIOS disabling turbo mode once
