Merge tag 'pm-4.9-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
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)" * tag 'pm-4.9-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: PM / sleep: don't suspend parent when async child suspend_{noirq, late} fails PM / sleep: fix device reference leak in test_suspend cpupower: Correct return type of cpu_power_is_cpu_online() in cpufreq-set
