Pero usb_deauthorize_interface() no se puede completar hasta que se haya liberado el bloqueo del dispositivo, y el bloqueo no se liberar\u00e1 hasta que haya finalizado la eliminaci\u00f3n. El mecanismo proporcionado por sysfs para evitar este tipo de punto muerto es utilizar la funci\u00f3n sysfs_break_active_protection(), que le dice a sysfs que no espere la devoluci\u00f3n de llamada del atributo.
