Merge branch 'for-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux
Pull thermal management fixes from Zhang Rui: "Specifics: - Fix a problem that Intel SoC DTS thermal driver does not work when CONFIG_THERMAL_INT340X is not set. - Fix a NULL pointer dereference when processor_thermal_device driver is loaded on a platform without ACPI support" * 'for-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux: int340x_thermal/processor_thermal_device: return failure when ACPI/int340x_thermal: enumerate INT3401 for Intel SoC DTS thermal driver ACPI/int340x_thermal: enumerate INT340X devices even if they're not in _ART/_TRT
