[alsa-devel] [PATCH] cs4231-lib: add support for Opti93x codec

From: Krzysztof Helt <krzysztof.h1 at wp.pl>
This patch adds support for WSS compatible Opti93x
codec to the cs4231-lib.
Signed-off-by: Krzysztof Helt <krzysztof.h1 at wp.pl>
---
This allows to remove cs4231 duplicated code from
the opti93x driver. It is almost half of the opti driver.
The opti93x must use its own interrupt handler
so it needs also the overrange function. That's why
it is exported.
The next patch will convert the opti93x driver to
use the cs4231 library instead of its own code.
The cs4231 library (and ad1848's) gets improved
with Rene's and Trent's help so this should improve
the opti driver as well.
Regards,
Krzysztof
