Sorry. I just found we need to set codec->cache_sync = 1 in SND_SOC_BIAS_OFF. Otherwise, snd_soc_cache_sync won't sync work.
Will send a v2 soon.

This serial converts the wm8xxx codec drivers to use snd_soc_cache_sync. I don't have these hardware, but I assume Mark has all these hardware. These patches are UNTESTED. I'd appreciate if someone can test them. (Current code is broken anyway, thus we need convert to use new API. )
