Merge tag 'pm-5.15-rc1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull more power management updates from Rafael Wysocki:
"These improve hybrid processors support in intel_pstate, fix an issue
in the core devices PM code, clean up the handling of dedicated wake
IRQs, update the Energy Model documentation and update MAINTAINERS.
Specifics:
- Make the HWP performance levels calibration on hybrid processors in
intel_pstate more straightforward (Rafael Wysocki).
- Prevent the PM core from leaving devices in suspend after a failing
system-wide suspend transition in some cases when driver PM flags
are used (Prasad Sodagudi).
- Drop unused function argument from the dedicated wake IRQs handling
code (Sergey Shtylyov).
- Fix up Energy Model kerneldoc comments and include them in the
Energy Model documentation (Lukasz Luba).
- Use my kernel.org address in MAINTAINERS insead of the personal one
(Rafael Wysocki)"
