[alsa-devel] [PATCH 9/xx] wss_lib: use wss pcm code instead of ad1848 one

From: Krzysztof Helt <krzysztof.h1 at wp.pl>
Use the wss pcm code and kill the ad1848 pcm code.
Signed-off-by: Krzysztof Helt <krzysztof.h1 at wp.pl>
---
The next patch in the series of the wss_lib.
It brings another code reduction and the only
thing left in the ad1848_lib is detection code.
There is a small code added to the snd_wss_pcm()
with "temporary" comment. It is needed until
the detection/initialization is merged code (the
next patch I suppose). Also, the AD1848_LIB
selects the WSS_LIB in the Kconfig. This is
also temporary until the ad1848_lib is removed.
It works on cards I tested (Opti930, Sound Galaxy with
CS4231A codec and SC-6000 with the AD1848 codec).
Both playback and recording was tested.
