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
