From: Krzysztof Helt krzysztof.h1@wp.pl

Use the wss pcm code and kill the ad1848 pcm code.

Signed-off-by: Krzysztof Helt krzysztof.h1@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.
