[alsa-devel] [PATCH 08/11] wss_lib: use wss mixer code instead of ad1848 one
Krzysztof Helt
krzysztof.h1 at poczta.fm
Thu Jul 31 21:08:32 CEST 2008
From: Krzysztof Helt <krzysztof.h1 at wp.pl>
Use the wss mixer code and kill the ad1848 mixer code.
Signed-off-by: Krzysztof Helt <krzysztof.h1 at wp.pl>
---
Changes since previous version:
1. Nicer formatting of WSS_SINGLE/WSS_DOUBLE and TLV
macros.
2. TLV macro definitions moved to the wss.h directly.
