Pull power management fixes from Rafael Wysocki:
 "These revert a recent cpufreq schedutil governor change that turned
  out to be problematic and fix a few minor issues in cpufreq, cpuidle
  and the Exynos devfreq drivers.

  Specifics:

   - Revert a recent cpufreq schedutil governor change that caused some
     systems to behave undesirably (Rafael Wysocki).

   - Fix a cpufreq conservative governor issue introduced during the
     3.10 cycle that prevents it from working as expected in some
     situations (Tomasz Wilczyński).

   - Fix an error code path in the generic cpuidle driver for DT-based
     systems (Christophe Jaillet).

   - Fix three minor issues in devfreq drivers for Exynos (Arvind Yadav,
     Krzysztof Kozlowski)"
