Pull power management fixes from Rafael Wysocki:
 "These fix two bugs in error code paths in the PM core (system-wide
  suspend of devices), a device reference leak in the boot-time suspend
  test code and a cpupower utility regression from the 4.7 cycle.

  Specifics:

   - Prevent the PM core from attempting to suspend parent devices if
     any of their children, whose suspend callbacks were invoked
     asynchronously, have failed to suspend during the "late" and
     "noirq" phases of system-wide suspend of devices (Brian Norris).

   - Prevent the boot-time system suspend test code from leaking a
     reference to the RTC device used by it (Johan Hovold).

   - Fix cpupower to use the return value of one of its library
     functions correctly and restore the correct behavior of it when
     used for setting cpufreq tunables broken during the 4.7 development
     cycle (Laura Abbott)"
