PARPORT_UNREGISTER_D(9) 			Parallel Port Devices			      PARPORT_UNREGISTER_D(9)

NAME
       parport_unregister_driver - deregister a parallel port device driver

SYNOPSIS
       void parport_unregister_driver(struct parport_driver * drv);

ARGUMENTS
       drv
	   structure describing the driver that was given to parport_register_driver

DESCRIPTION
       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.
