.BI "void parport_unregister_driver(struct\ parport_driver\ *\ " "drv" ");"
.SH "ARGUMENTS"
.PP
\fIdrv\fR
.RS 4

.SH "DESCRIPTION"
.PP
This should be called by a parallel port device driver that has registered itself using
\fBparport_register_driver\fR
when it is about to be unloaded\&.
.PP
When it returns, the driver\*(Aqs
\fBattach\fR
routine will no longer be called, and for each port that
\fBattach\fR
was called for, the
\fBdetach\fR
routine will have been called\&.
.PP
All the driver\*(Aqs
\fBattach\fR
and
\fBdetach\fR
calls are guaranteed to have finished by the time this function returns\&.
