This will still disable the FLL if there's an analogue bypass path active. I'd suggest changing enable() and disable() to reference count.
if (dapm->bias_level == SND_SOC_BIAS_STANDBY)return imx_wm8962_enable_fll(codec_dai, 44100,SNDRV_PCM_FORMAT_S16_LE);
It might be slightly nicer to keep the static variable for the frequency - that way if we start up due to set_bias_level() we'll keep the last rate played which might be more likely to avoid locking playbacks out. Very minor thing though, I wouldn't worry about it.
