[PATCH 00/26] thermal: cpu_cooling: Fixes and cleanups

[Viresh Kumar <viresh.kumar@linaro.org>]

Hi Eduardo,

As you know I got into fixing cpu_cooling.c due to some cpufreq issues you and
Lukasz were struggling with. I found some issues in cpu_cooling then and here
are the fixes/cleanups.

Sorry for the long list. Haven't broken them into smaller sets as most of the
patches are very small, easy to review and inter-dependent. Only few of them
should take more time to review. If this doesn't work out, let me know and I
will try to send separate inter-dependent sets.

Just apply whatever looks fine and I will update/resend the ones left in V2 if
at required.

First few are updates to platform drivers. Exynos fails to register after few
patches in this series as it doesn't handle -EPROBE_DEFER properly (reported
that in reply to your patch as well). Others weren't setting clip_cpus properly
and are fixed.

Next ones are cleanups of cpu_cooling.c to get things properly organized.

Let me know if I screwed it up completely.

Tested-on: Exynos5250 (Dual ARM Cortex A15).
Rebased-over: v3.18-rc6
