Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux
Pull thermal management updates from Zhang Rui:
- Remove the 'module' Kconfig option for thermal subsystem framework
because the thermal framework are required to be ready as early as
possible to avoid overheat at boot time (Daniel Lezcano)
- Fix a bug that thermal framework pokes disabled thermal zones upon
resume (Wei Wang)
- A couple of cleanups and trivial fixes on int340x thermal drivers
(Srinivas Pandruvada, Zhang Rui, Sumeet Pawnikar)
* 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux:
drivers: thermal: processor_thermal: Downgrade error message
mlxsw: Remove obsolete dependency on THERMAL=m
hwmon/drivers/core: Simplify complex dependency
thermal/drivers/core: Fix typo in the option name
thermal/drivers/core: Remove depends on THERMAL in Kconfig
thermal/drivers/core: Remove module unload code
thermal/drivers/core: Remove the module Kconfig's option
thermal: core: skip update disabled thermal zones after suspend
thermal: make device_register's type argument const
thermal: intel: int340x: processor_thermal_device: simplify to get driver data
thermal/int3403_thermal: favor _TMP instead of PTYP
