Is this now done in generic code? Not necessary anymore? Was no comment

These kinds of switches are just about the only time you get to
knowingly ignore coding style and you forego the opportunity? Tsssk...

For those that come after -- those error ifs are split when they are
turned into snd_wss_create() later.

Same.
Throughout this patch there's also still the comment about ignoring the
80-column thing with these macros. The cmi8330.c ones are a wonderful
example of how much worse it gets. It's horrible.

Ah. This fixes up one of my comments from yesterday already. If this
finds its way into 3, it should ofcourse be gone here.

If you'll be posting a V2 series, might as well fold 11/10 in here.

Comment about the switch getting uglier again.

Mmm. This was changed from a udelay(500) in the ad1848 case. It would be
better to keep these kinds of really functional changes seperated out.

The original snd_ad1848_probe() had this below the below tests (which
were also outside the spinlock)

This one could also wind up different. Originally, snd_ad1848_probe()
would conclude CS4248 immediately upon (rev & 0x80) without doing that
register test. It's probably all fine, but snd_ad1848 function changed
very significantly in the move and I'd rather it not do that. A patch
12 alone is much easier reviewable and any possible difficulty much
easier bisectable. Could you do that?
*** 0011-wss-fix-capture-formats-limitations.patch
Can be folded, but otherwise no comments...
Will also put a next series through some tests here locally. I'l test at
least a few OPTi 92x cards since I don't see these in your report. Any
specific hardware you'd want tested more than others? I might have it.
Rene.
