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.
