Merge tag 'pm-4.18-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management fixes from Rafael Wysocki:
 "These fix up recently added features (the Kryo cpufreq driver and
  performance states coverage in the generic power domains framework),
  add missing documentation for a recently added sysfs knob in the
  intel_pstate driver and fix an error in its documentation.

  Specifics:

   - Fix the initialization time error handling in the recently added
     Kryo cpufreq driver (Dan Carpenter).

   - Fix up the recently added coverage of performance states in the
     generic power domains (genpd) framework (Viresh Kumar).

   - Add missing documentation of the new hwp_dynamic_boost sysfs knob
     in the intel_pstate driver (Rafael Wysocki).

   - Fix incorrect sysfs path in the intel_pstate driver documentation
     (Rafael Wysocki)"
