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

Pull thermal management fix from Zhang Rui:
 "A single revert from a recently introduced problem.

  Specifics:

  Commit 7611fb68 ("thermal: thermal_hwmon: Convert to
  hwmon_device_register_with_info()"), which was introduced in 4.10-rc5,
  uses new hwmon API. But this breaks some soc thermal driver because
  the new hwmon API has a strict rule for the hwmon device name. Revert
  the offending commit as a quick solution for 4.10"

* 'for-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux:
  Revert "thermal: thermal_hwmon: Convert to hwmon_device_register_with_info()"
