Uwe Kleine-König ba8a86e4da leds: trigger/tty: Use led_set_brightness_sync() from workqueue 
led_set_brightness() involves scheduling a workqueue. As here the led's
brightness setting is done in context of the trigger's workqueue this is
unjustified overhead and it's more sensible to use
led_set_brightness_sync().
