.SH "DESCRIPTION"
.PP
Creates an AC97 bus component.  An ac97_bus_t instance is newly
allocated and initialized.
.PP
The ops table must include valid callbacks (at least read and
write).  The other callbacks, wait and reset, are not mandatory.
.PP
The clock is set to 48000.  If another clock is needed, set
(*rbus)->clock manually.
.PP
The AC97 bus instance is registered as a low-level device, so you don't
have to release it manually.
.PP
Returns zero if successful, or a negative error code on failure.
