I was operating under the assumption that those comments from hdac.c,
about the snd_hda driver badly needing a complete rewrite because it was
insufficiently, well, bussed? Yeah, bussed meant that code rework was
If you even know what that comment about the busses being less than they
might be means, IF you could point me at any driver that you personally
think shows a more *ideal* setup, it would at least make me aware of
what's really wanted. You don't need to describe it yourself, I know
that'd be a major bore to do that for me, and I could probably learn as
well by just reading code that illustrates what things *should* be.
