Merge tag 'pm-4.17-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management fixes from Rafael Wysocki:
 "These are a Low Power S0 Idle quirk, a hibernation handling fix for
  the PCI bus type and a brcmstb-avs-cpufreq driver fixup removing
  development debug code from it.

  Specifics:

   - Blacklist the Low Power S0 Idle _DSM on ThinkPad X1 Tablet(2016)
     where it causes issues and make it use ACPI S3 which works instead
     of the non-working suspend-to-idle by default (Chen Yu).

   - Fix the handling of hibernation in the PCI core for devices with
     the DPM_FLAG_SMART_SUSPEND flag set to fix a regression affecting
     intel-lpss I2C devices (Mika Westerberg).

   - Drop development debug code from the brcmstb-avs-cpufreq driver
     (Markus Mayer)"
