PARPORT_REMOVE_PORT(9)					       Parallel Port Devices					    PARPORT_REMOVE_PORT(9)

NAME
       parport_remove_port - deregister a parallel port

SYNOPSIS
       void parport_remove_port(struct parport * port);

ARGUMENTS
       port
	   parallel port to deregister

DESCRIPTION
       When a parallel port driver is forcibly unloaded, or a parallel port becomes inaccessible, the port driver must call this function in order
       to deal with device drivers that still want to use it.

       The parport structure associated with the port has its operations structure replaced with one containing 'null' operations that return
       errors or just don't do anything.

       Any drivers that have registered themselves using parport_register_driver are notified that the port is no longer accessible by having
       their detach routines called with port as the parameter.
