  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.
