Subject: [GIT PULL] Power management fixes for v4.17-rc5

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-4.17-rc5

with top-most commit ef050374e1eedec45bd260e0ac9eb98f699267d2

 Merge branches 'pm-pci' and 'pm-docs'

on top of commit 75bc37fefc4471e718ba8e651aa74673d4e0a9eb

 Linux 4.17-rc4

to receive power management fixes for 4.17-rc5.

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).

Thanks!
