Hi Fabio,

Leonard (Cc'ed) noticed that commit in $subject looks very strange.

For example:

@@ -139,7 +140,7 @@ static int imx_wm8962_late_probe(struct snd_soc_card *card)
 {
        struct snd_soc_pcm_runtime *rtd;
        struct snd_soc_dai *codec_dai;
-       struct imx_priv *priv = &card_priv;
+       struct imx_priv *priv = snd_soc_card_get_drvdata(card);
        struct imx_wm8962_data *data = snd_soc_card_get_drvdata(card);

So, now data and priv point to the same memory area but they are completely
different structures!

Unless we are missing something this is obviously a bug. I will try to have a look at
the end of the week, but any comments are welcome.

I think the fix would be to have one global priv structure and to unify imx_wm8962_data
with imx_priv.

thanks,
Daniel.
