Merge branch 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux
Pull thermal management update from Zhang Rui: "Highlights: - Introduction of thermal policy support, together with three new thermal governors, including step_wise, user_space, fire_share. - Introduction of ST-Ericsson db8500_thermal driver and ST-Ericsson db8500_cpufreq_cooling driver. - Thermal Kconfig file and Makefile refactor. - Fixes for generic thermal layer, generic cpucooling, rcar thermal driver and Exynos thermal driver." * 'release' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux: (36 commits) Thermal: Fix DEFAULT_THERMAL_GOVERNOR Thermal: fix a NULL pointer dereference when generic thermal layer is built as a module thermal: rcar: add rcar_zone_to_priv() macro thermal: rcar: fixup the unit of temperature thermal: cpu cooling: allow module builds thermal: cpu cooling: use const parameter while registering Thermal: Add ST-Ericsson DB8500 thermal properties and platform data. Thermal: Add ST-Ericsson DB8500 thermal driver. drivers/thermal/Makefile refactor Exynos: Add missing dependency Refactor drivers/thermal/Kconfig thermal: cpu_cooling: Make 'notify_device' static Thermal: Remove the cooling_cpufreq_list. Thermal: fix bug of counting cpu frequencies. Thermal: add indent for code alignment. thermal: rcar_thermal: remove explicitly used devm_kfree/iounap() thermal: user_space: Add missing static storage class specifiers thermal: fair_share: Add missing static storage class specifiers thermal: step_wise: Add missing static storage class specifiers Thermal: Fix oops and unlocking in thermal_sys.c ...
