Merge branch 'for-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux

Pull thermal fixes from Zhang Rui:

 - Fix cpu_cooling to have separate thermal_cooling_device_ops
   structures for cpus with and without power model, to avoid NULL
   dereference in cpufreq_state2power.  From Brendan Jackman.

 - Fix a possible NULL dereference in imx_thermal driver.  From Corentin
   LABBE.

 - Another two trivial fixes, one typo fix and one deleting module
   owner.  From Caesar Wang and Markus Elfring.

* 'for-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux:
  thermal: imx: fix a possible NULL dereference
  thermal: trivial: fix the typo
  Thermal-INT3406: Delete owner assignment
  thermal: cpu_cooling: Fix NULL dereference in cpufreq_state2power
