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 7611fb68062f ("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:
