Pull thermal management updates from Zhang Rui: - Thermal core code reorganization and cleanup. Two new files are created for thermal sysfs I/F code and thermal helper functions (Eduardo Valentin). - Sanitize hotplug and locking for x86_pkg_temp driver (Thomas Gleixner) - Update MAINTAINER file for pwm-fan driver and Samsung thermal driver (Lukasz Majewski) - Fix module auto-load for max77620, tango and db8500 thermal driver (Javier Martinez Canillas) - Fix a bug that thermal hwmon sysfs I/F returns wrong critical trip point temperature value (Krzysztof Kozlowski) - Add Skylake PCH 100 series support for intel_pch_thermal driver (OGAWA Hirofumi) - Small fixes and cleanups for platform thermal drivers (Julia Lawall, Luis Henriques, Leo Yan, Stephen Boyd, Shawn Lin, Javi Merino and Lukasz Luba) * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux: (76 commits) MAINTAINERS: Samsung: Update maintainer for PWM FAN and SAMSUNG THERMAL thermal/x86 pkg temp: Convert to hotplug state machine thermal/x86_pkg_temp: Sanitize package management thermal/x86_pkg_temp: Move work into package struct thermal/x86_pkg_temp: Move work scheduled flag into package struct thermal/x86_pkg_temp: Sanitize locking thermal/x86_pkg_temp: Cleanup code some more thermal/x86_pkg_temp: Cleanup namespace thermal/x86_pkg_temp: Get rid of ref counting thermal/x86_pkg_temp: Sanitize callback (de)initialization thermal/x86_pkg_temp: Replace open coded cpu search thermal/x86_pkg_temp: Remove redundant package search thermal/x86_pkg_temp: Cleanup thermal interrupt handling thermal: hwmon: Properly report critical temperature in sysfs devfreq_cooling: pass a pointer to devfreq in the power model callbacks devfreq_cooling: make the structs devfreq_cooling_xxx visible for all dt-bindings: rockchip-thermal: fix the misleading description thermal: rockchip: improve the warning log thermal: db8500: Fix module autoload thermal: tango: Fix module autoload ...
