- Fix tasks freezer deadlock in de_thread() that occurs if one
of its sub-threads has been frozen already (Chanho Min).
- Avoid registering a platform device by the ti-cpufreq driver
on platforms that cannot use it (Dave Gerlach).
- Fix a mistake in the ti-opp-supply operating performance points
(OPP) driver that caused an incorrect reference voltage to be
used and make it adjust the minimum voltage dynamically to avoid
hangs or crashes in some cases (Keerthy).
- Fix issues related to compiler flags in the cpupower utility
and correct a linking problem in it by renaming a file with
a duplicate name (Jiri Olsa, Konstantin Khlebnikov).

Pull power management fixes from Rafael Wysocki:
"These fix two issues in the Operating Performance Points (OPP)
framework, one cpufreq driver issue, one problem related to the tasks
freezer and a few build-related issues in the cpupower utility.
Specifics:
- Fix tasks freezer deadlock in de_thread() that occurs if one of its
sub-threads has been frozen already (Chanho Min).
- Avoid registering a platform device by the ti-cpufreq driver on
platforms that cannot use it (Dave Gerlach).
- Fix a mistake in the ti-opp-supply operating performance points
(OPP) driver that caused an incorrect reference voltage to be used
and make it adjust the minimum voltage dynamically to avoid hangs
or crashes in some cases (Keerthy).
- Fix issues related to compiler flags in the cpupower utility and
correct a linking problem in it by renaming a file with a duplicate
name (Jiri Olsa, Konstantin Khlebnikov)"
