leds: use led_set_brightness in led_trigger_event
Fix led_trigger_event() to use led_set_brightness() instead of __led_set_brightness(), so that any pending blink timer is stopped before setting the new brightness value. Without this fix LED status may be overridden by a pending timer. This allows a trigger to use a mix of led_trigger_event(), led_trigger_blink() and led_trigger_blink_oneshot() without races. (applied over: leds: Rename led_brightness_set() to led_set_brightness()) Signed-off-by: Fabio Baltieri <fabio.baltieri@gmail.com> Cc: Shuah Khan <shuahkhan@gmail.com> Signed-off-by: Bryan Wu <bryan.wu@canonical.com>
