Wysocki In preparation for a subsequent change that will switch over the thermal core to using a mutex guard for managing thermal_governor_lock, move the code running in thermal_zone_device_register_with_trips() under that lock into a separate function called thermal_zone_init_governor(). While at it, drop a useless comment. No intentional functional impact. Signed-off-by: Rafael J.
