led_trigger_event() is always called. In this case, if the LED trigger is set to the SD Card, the trigger will occur even when the SD card is not connected and the LED will blink. In case of SD Card, it is judged based on Card Detection information and changes to generate LED trigger only when SD Card is connected.
