LEDs are registered using devm_led_classdev_register() and automatically unregistered after module's remove(). led_classdev_unregister() calls led_set_brightness() to turn off the LEDs and module's appropriate callback uses resources those were destroyed already in module's remove(). So explicitly unregister LEDs at module shutdown.
