.SH "NAME"

.SH "DESCRIPTION"
.PP
We do this in two parts, like we do
\fBdevice_register\fR\&. First, we remove it from all the subsystems with
\fBdevice_del\fR, then we decrement the reference count via
\fBput_device\fR\&. If that is the final reference count, the device will be cleaned up via
\fBdevice_release\fR
above\&. Otherwise, the structure will stick around until the final reference to the device is dropped\&.
