In smdk_hw_params(), 'bfs' is initialized and assigned bits based on params_width, but never used.
We could have removed the whole switch case but then driver might be relying on checking bits, so I have kept the case for now.
sound/soc/samsung/smdk_wm8580.c: In function ‘smdk_hw_params’: sound/soc/samsung/smdk_wm8580.c:35:6: warning: variable ‘bfs’ set but not used [-Wunused-but-set-variable] int bfs, rfs, ret;
