[alsa-devel] [PATCH] wm8974: fix a wrong bit definition

[Guennadi Liakhovetski]

The wm8974 datasheet defines BUFIOEN as bit 2.

no idea if this would break anything, so, please test. Maybe the correct 
fix would be to actually use a correct name for bit 4, but who wants to 
enable Mic bias when putting bias into standby?...
