Merge tag 'pm-4.17-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management fixes from Rafael Wysocki:
"These fix two PCI power management regressions from the 4.13 cycle and
one cpufreq schedutil governor bug introduced during the 4.12 cycle,
drop a stale comment from the schedutil code and fix two mistakes in
docs.
Specifics:
- Restore device_may_wakeup() check in pci_enable_wake() removed
inadvertently during the 4.13 cycle to prevent systems from drawing
excessive power when suspended or off, among other things (Rafael
Wysocki).
- Fix pci_dev_run_wake() to properly handle devices that only can
signal PME# when in the D3cold power state (Kai Heng Feng).
- Fix the schedutil cpufreq governor to avoid using UINT_MAX as the
new CPU frequency in some cases due to a missing check (Rafael
Wysocki).
- Remove a stale comment regarding worker kthreads from the schedutil
cpufreq governor (Juri Lelli).
- Fix a copy-paste mistake in the intel_pstate driver documentation
(Juri Lelli).
- Fix a typo in the system sleep states documentation (Jonathan
Neuschäfer)"
