Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux

Pull thermal management updates from Zhang Rui:

 - Improve thermal cpu_cooling interaction with cpufreq core.

   The cpu_cooling driver is designed to use CPU frequency scaling to
   avoid high thermal states for a platform. But it wasn't glued really
   well with cpufreq core.

   For example clipped-cpus is copied from the policy structure and its
   much better to use the policy->cpus (or related_cpus) fields directly
   as they may have got updated. Not that things were broken before this
   series, but they can be optimized a bit more.

   This series tries to improve interactions between cpufreq core and
   cpu_cooling driver and does some fixes/cleanups to the cpu_cooling
   driver. (Viresh Kumar)

 - A couple of fixes and cleanups in thermal core and imx, hisilicon,
   bcm_2835, int340x thermal drivers. (Arvind Yadav, Dan Carpenter,
   Sumeet Pawnikar, Srinivas Pandruvada, Willy WOLFF)
