Al eliminar el controlador, sound/soc/codecs/hdmi-codec.c llama a plugged_cb con NULL como funci\u00f3n de devoluci\u00f3n de llamada y codec_dev, como se observa en su funci\u00f3n hdmi_remove. El auxiliar de audio HDMI intenta entonces llamar a dicho puntero de funci\u00f3n nulo, pero produce un error. Para solucionar esto, ejecute la devoluci\u00f3n de llamada solo si fn no es nulo.
