ieee1284_release — release a port
void ieee1284_release(struct parport *port);
This function undoes the effect of ieee1284_claim(3) by releasing the port for use by other drivers. It is good practice to release the port whenever convenient. If it is never convenient to do so, the F1284_EXCL flag should be specified at initialization.
