.TH "DRIVER_UNREGISTER" "" "06 October 2005" "" ""

.SH NAME
driver_unregister \- remove driver from system.
.SH SYNOPSIS
"SYNOPSIS"
.sp
\fB
.sp
void driver_unregister  (struct device_driver * \fIdrv\fB);
\fR
.SH "ARGUMENTS"
.TP
\fB\fIdrv\fB\fR
driver.
.SH "DESCRIPTION"
.PP
Again, we pass off most of the work to the bus-level call.
.PP
Though, once that is done, we attempt to take \fIdrv\fR->unload_sem.
This will block until the driver refcount reaches 0, and it is
released. Only modular drivers will call this function, and we 
have to guarantee that it won't complete, letting the driver 
unload until all references are gone.
