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

Pull thermal updates from Zhang Rui:
 "Thermal core and intel thermal drivers:

   - convert thermal sysfs attributes to use DEVICE_ATTR_{RO|RW|WO}()
     variants (Viresh Kumar)

   - update license to SPDX format (Lina Iyer)

   - add GeminiLake support for int340x processor_thermal driver (Sumeet
     Pawnikar)

   - prevent error in reading trip hysteresis attribute for int340x
     thermal driver (Srinivas Pandruvada)"

* 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux:
  thermal: int340x: processor_thermal: Add GeminiLake support
  drivers: thermal: Update license to SPDX format
  thermal: int340x: Prevent error in reading trip hysteresis attribute
  thermal: Use DEVICE_ATTR_{RO|RW|WO}() variants
  thermal: Shorten name of sysfs callbacks
