From: Krzysztof Helt <krzysztof.h1@xxxxx>
Use the wss_dout function which does not mess
shadowed register values during chip probing.
Otherwise, user ends up with stupid mixer settings
after driver loading.

Especially, the recording settings are messed up like
left channel recording from different source than
right channel.
