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)"
