From dc8b73ebe543f53ec78507a9d0d37073773f6157 Mon Sep 17 00:00:00 2001 From: Daniel Wagner Date: Fri, 16 Sep 2016 10:07:36 +0200 Subject: 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").
