hwmon: (adt7470) No need for additional synchronization on kthread_stop()
The kthread_stop() waits for the thread to exit. There is no need for an additional synchronization needed to join on the kthread. The completion was added by 89fac11cb3e7 ("adt7470: make automatic fan control really work"). Signed-off-by: Daniel Wagner <daniel.wagner@bmw-carit.de> Cc: Darrick J.
