If the default trigger then later gets replaced by a trigger which does check LED_INIT_DEFAULT_TRIGGER, such as "timer" then that trigger will behave as if it is the default trigger which it should not do. To fix this clear the LED_INIT_DEFAULT_TRIGGER flag when clearing the current trigger, so that it will not be set for any subsequently set (non default) triggers.
