Merge tag 'pm-fixes-4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull two power management fixes from Rafael Wysocki:
"This is the change making /proc/cpuinfo on x86 report current CPU
frequency in "cpu MHz" again in all cases and an additional one
dealing with an overzealous check in one of the helper routines in the
runtime PM framework"
* tag 'pm-fixes-4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
PM / runtime: Drop children check from __pm_runtime_set_status()
x86 / CPU: Always show current CPU frequency in /proc/cpuinfo
