Merge branch 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal

Pull thermal fixes from Eduardo Valentin:
"In this -rc still very minor changes:

- Lee Jones fixes compilation warning in sti thermal driver
- Marjus Elfring removes unnecessary checks in exynos thermal driver
(as per coccinelle)
- Now we always update cpufreq policies, and thus get (hopefully)
always in sync with cpufreq, thanks to Yadwinder"

* 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal:
thermal: Exynos: Deletion of unnecessary checks before two function calls
thermal: sti: Ignore suspend/resume functions when !PM_SLEEP
thermal: cpu_cooling: Update always cpufreq policy with thermal constraints
