Please, could you also initialize snd_soc_card->components? It may be useful
to pass the codec identification to the user space like:
.components = "codec:wm9712"
The passed information should be consistent. You may look into the Intel ASoC
drivers for the examples (card->components initialization). There are also
hints about the number of connected microphones ("cfg-mic:2" - configuration
with 2 microphones) or the codec purpose ("hs:rt711" - headset codec is RT711)
etc.
