parport_unregister_driver — deregister a parallel port device driver
void parport_unregister_driver ( | struct parport_driver * drv); |
This should be called by a parallel port device driver that
has registered itself using parport_register_driver when it
is about to be unloaded.
When it returns, the driver's attach routine will no longer
be called, and for each port that attach was called for, the
detach routine will have been called.
All the driver's attach and detach calls are guaranteed to have
finished by the time this function returns.
