Thomas Weißschuh 93ac74cd6f leds: triggers: Flush pending brightness before activating trigger ... [ Upstream commit ab477b766e ] The race fixed in timer_trig_activate() between a blocking set_brightness() call and trigger->activate() can affect any trigger. So move the call to flush_work() into led_trigger_set() where it can avoid the race for all triggers. Fixes: 0db37915d9 ("leds: avoid races with workqueue") Fixes: 8c0f693c6e ("leds: avoid flush_work in atomic context") Cc: stable@vger.kernel.org Tested-by: Dustin L.
