Merge tag 'pm-7.1-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management fixes from Rafael Wysocki:
 "These address some remaining fallout after introducing dynamic EPP
  support in the amd-pstate driver during the current development cycle:

   - Restore allowing writing EPP of 0 when in performance mode in the
     amd-pstate driver which was unnecessarily disallowed by one of the
     recent updates (Mario Limonciello)

   - Remove stale documentation of the epp_cached field in struct
     amd_cpudata that has been dropped recently (Zhan Xusheng)"
