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
