Pull power management fixes from Rafael Wysocki:
"These fix one more issue related to the recent RCU-lockdep changes, a
typo in documentation and add a missing return statement to
intel_pstate.
Specifics:
- Fix up RCU usage for cpuidle on the ARM imx6q platform (Ulf
Hansson)
- Fix typo in the PM documentation (Yoann Congal)
- Add return statement that is missing after recent changes in the
intel_pstate driver (Zhang Rui)"
