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

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)
