Merge tag 'staging-3.18-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging (2014-11-28 16:08:09 -0800)
Specifics:
- In this pull, I am including a series of fixes that was supposed to make 3.18, but I decided
to send them for v3.19. I left for v3.19 because the required changes modified a couple of APIs.
Therefore, the redesign had to be done properly. The major fix here is to have proper sequencing
between cpufreq layer and cpu cooling registration. A take away of this fix is an improvement in
the thermal drivers code. Thermal drivers that require cpu cooling do not need to check for
cpufreq layer. The requirement now is to propagate the error code, if any, while registering
cpu cooling device. Thanks to Viresh for implementing the required CPUfreq changes.
- While in the subject, Viresh took the opportunity to review the cpu cooling code from a
cpufreq layer user perspective, which resulted in several cleanups.
- The content in this pull depends on CPUfreq refactoring done by Viresh, which is part of
the pull sent by Rafael J. W.:
