Linus Torvalds 6876eb3720 Power management fixes for v4.14-rc2
- Fix a regression in cpufreq on systems using DT as the source of
    CPU configuration information where two different code paths
    attempt to create the cpufreq-dt device object (there can be only
    one) and fix up the "compatible" matching for some TI platforms
    on top of that (Viresh Kumar, Dave Gerlach).
 
  - Fix an initialization time memory leak in cpuidle on ARM which
    occurs if the cpuidle driver initialization fails (Stefan Wahren).
 
  - Fix a PM core function that checks whether or not there are any
    system suspend/resume callbacks for a device, but forgets to
    check legacy callbacks which then may be skipped incorrectly
    and the system may crash and/or the device may become unusable
    after a suspend-resume cycle (Rafael Wysocki).
 
  - Fix request type validation for latency tolerance PM QoS requests
    which may lead to unexpected behavior (Jan Schönherr).
 
  - Fix a broken link to PM documentation from a header file and a
    typo in a PM document (Geert Uytterhoeven, Rafael Wysocki).

Pull power management fixes from Rafael Wysocki:
 "These fix a cpufreq regression introduced by recent changes related to
  the generic DT driver, an initialization time memory leak in cpuidle
  on ARM, a PM core bug that may cause system suspend/resume to fail on
  some systems, a request type validation issue in the PM QoS framework
  and two documentation-related issues.

  Specifics:

   - Fix a regression in cpufreq on systems using DT as the source of
     CPU configuration information where two different code paths
     attempt to create the cpufreq-dt device object (there can be only
     one) and fix up the "compatible" matching for some TI platforms on
     top of that (Viresh Kumar, Dave Gerlach).

   - Fix an initialization time memory leak in cpuidle on ARM which
     occurs if the cpuidle driver initialization fails (Stefan Wahren).

   - Fix a PM core function that checks whether or not there are any
     system suspend/resume callbacks for a device, but forgets to check
     legacy callbacks which then may be skipped incorrectly and the
     system may crash and/or the device may become unusable after a
     suspend-resume cycle (Rafael Wysocki).

   - Fix request type validation for latency tolerance PM QoS requests
     which may lead to unexpected behavior (Jan Schönherr).

   - Fix a broken link to PM documentation from a header file and a typo
     in a PM document (Geert Uytterhoeven, Rafael Wysocki)"
