The ams-delta asoc driver doesn't use snd_soc_register_card() so far, 
but relays solely on soc_probe() doing this for it, which in turn 
expects to find a snc_soc_card structure in drvdata. How is it supposed 
to find that structure if I pass it over platform data instead? Am I 
missing something?
