 parport_claim and parport_release in order to use the port.
 
+The ('name') argument is the name of the device that appears in /proc

 This function will register three callbacks into your driver:
 'preempt', 'wakeup' and 'irq'.  Each of these may be NULL in order to
 indicate that you do not want a callback.
