[PATCH] [207/275] ALSA: ctxfi - Fix SPDIF status retrieval

[Andi Kleen]

2.6.35-longterm review patch.  If anyone has any objections, please let me know.

------------------
From: Przemyslaw Bruski <pbruskispam@xxxxx>

commit f164753a263bfd2daaf3e0273b179de7e099c57d upstream.

SDPIF status retrieval always returned the default settings instead of
the actual ones.
