Merge branch 'for-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux
Pull thermal management fixes from Zhang Rui: - fix an ordering issue in cpu cooling that cooling device is registered before it's ready (freq_table being populated). (Lukasz Luba) - fix a missing comment update (Caesar Wang) * 'for-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux: thermal: add the note for set_trip_temp thermal: cpu_cooling: fix improper order during initialization
