Sorry to be too late to join the review (as I've been too busy and in
other troubles...)

SST driver has been once (sort of) posted and reviewed, but stalled
since then.  But in general I'm not against merging to the sound main
tree at all.  The only reason that it didn't occur was that the
activity just stopped somehow.

Anyway, I'm going to review in the next week or so.  Then maybe we can
move it to sound/ directory (e.g. creating sound/platform/x86
directory) before rc1, unless you'd like to keep the stuff rather in
staging tree.
