Merge tag 'pm-5.0-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management fixes from Rafael Wysocki:
"These fix a PM-runtime framework regression introduced by the recent
switch-over of device autosuspend to hrtimers and a mistake in the
"poll idle state" code introduced by a recent change in it.
Specifics:
- Since ktime_get() turns out to be problematic for device
autosuspend in the PM-runtime framework, make it use
ktime_get_mono_fast_ns() instead (Vincent Guittot).
- Fix an initial value of a local variable in the "poll idle state"
code that makes it behave not exactly as expected when all idle
states except for the "polling" one are disabled (Doug Smythies)"
* tag 'pm-5.0-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
cpuidle: poll_state: Fix default time limit
PM-runtime: Fix deadlock with ktime_get()
