Wysocki The code is somewhat cleaner if struct thermal_trip_desc pointers are passed to thermal_bind_cdev_to_trip(), thermal_unbind_cdev_from_trip(), and print_bind_err_msg() instead of struct thermal_trip pointers, so modify it accordingly. No intentional functional impact. Signed-off-by: Rafael J.
