Thomas Weißschuh 93ac74cd6f leds: triggers: Flush pending brightness before activating trigger 
[ Upstream commit ab477b766edd3bfb6321a6e3df4c790612613fae ]

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")
