Linus Torvalds e37720e25d Power management fixes for v4.13-rc1
- Avoid clearing the PCI PME Enable bit for devices as a result of
    config space restoration which confuses AML executed afterward and
    causes wakeup events to be lost on some systems (Rafael Wysocki).
 
  - Fix the native PCIe PME interrupts handling in the cases when the
    PME IRQ is set up as a system wakeup one so that runtime PM remote
    wakeup works as expected after system resume on systems where that
    happens (Rafael Wysocki).
 
  - Fix the device PM QoS sysfs interface to handle invalid user input
    correctly instead of using an unititialized variable value as the
    latency tolerance for the device at hand (Dan Carpenter).
 
  - Get rid of one more rounding error from intel_pstate computations
    (Srinivas Pandruvada).
 
  - Fix the schedutil cpufreq governor to prevent it from possibly
    accessing unititialized data structures from governor callbacks in
    some cases on systems when multiple CPUs share a single cpufreq
    policy object (Vikram Mulukutla).
 
  - Fix the return values of probe routines in two devfreq drivers
    (Gustavo Silva).
 
  - Constify an attribute_group structure in devfreq (Arvind Yadav).

Pull power management fixes from Rafael Wysocki:
 "These fix a recently exposed issue in the PCI device wakeup code and
  one older problem related to PCI device wakeup that has been reported
  recently, modify one more piece of computations in intel_pstate to get
  rid of a rounding error, fix a possible race in the schedutil cpufreq
  governor, fix the device PM QoS sysfs interface to correctly handle
  invalid user input, fix return values of two probe routines in devfreq
  drivers and constify an attribute_group structure in devfreq.

  Specifics:

   - Avoid clearing the PCI PME Enable bit for devices as a result of
     config space restoration which confuses AML executed afterward and
     causes wakeup events to be lost on some systems (Rafael Wysocki).

   - Fix the native PCIe PME interrupts handling in the cases when the
     PME IRQ is set up as a system wakeup one so that runtime PM remote
     wakeup works as expected after system resume on systems where that
     happens (Rafael Wysocki).

   - Fix the device PM QoS sysfs interface to handle invalid user input
     correctly instead of using an unititialized variable value as the
     latency tolerance for the device at hand (Dan Carpenter).
