.TH "BUS_MATCH" "" "06 October 2005" "" ""

.SH NAME
bus_match \- check compatibility between device & driver.
.SH SYNOPSIS
"SYNOPSIS"
.sp
\fB
.sp
int bus_match  (struct device * \fIdev\fB, struct device_driver * \fIdrv\fB);
\fR
.SH "ARGUMENTS"
.TP
\fB\fIdev\fB\fR
device.
.TP
\fB\fIdrv\fB\fR
driver.
.SH "DESCRIPTION"
.PP
First, we call the bus's match function, which should compare
the device IDs the driver supports with the device IDs of the 
device. Note we don't do this ourselves because we don't know 
the format of the ID structures, nor what is to be considered
a match and what is not.
.PP
If we find a match, we call \fIdrv\fR->probe(\fIdev\fR) if it exists, and 
call \fBattach\fR above.
