[alsa-devel] ASoC: CPU DAI samsung-i2s.0 not registered

I think I have gotten around this problem using the code in the 
samsung/smdk_wm8994.c probe function :
         implant_dai.cpu_dai_name = NULL;
         implant_dai.cpu_of_node = of_parse_phandle(np, 
"samsung,i2s-controller", 0);
         implant_dai.platform_name = NULL;
         implant_dai.platform_of_node = implant_dai.cpu_of_node;

Now having problems with the codec registration :
     .codec_name    = "implant-codec",

ASoC: CODEC implant-codec not registered


I am looking for the magic here ...

Any ideas ?
