Subject: [PATCH v2 1/5] led: triggers: Break the for loop after default trigger is found

From: Jacek Anaszewski <jacek.anaszewski@...il.com>

It is of no avail to continue iterating through registered
triggers in the led_trigger_set_default() after the trigger to set
has been found. Add "break" statement to fix this omission.
