Merge tag 'pm-4.14-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management fixes from Rafael Wysocki:
 "These fix a deadlock in the operating performance points (OPP)
  framework introduced during the 4.11 cycle, more issues with duplicate
  device objects for cpufreq-dt and cpufreq documentation.

  Specifics:

   - Fix a deadlock in the operating performance points (OPP) framework
     caused by a notifier callback taking a lock that's already held by
     its caller (Viresh Kumar).

   - Prevent the ti-cpufreq and cpufreq-dt-platdev drivers from
     attempting to register conflicting device objects which triggers a
     warning from sysfs (Suniel Mahesh).

   - Drop a stale reference to a piece of intel_pstate documentation
     that's not in the tree any more (Rafael Wysocki)"
