Same behaviour with 3.4.0-rc6:
Framebuffer driver mx3fb configured for a 800x600 display:
soc-audio soc-audio: ASoC machine PhyCORE-ac97-audio should use snd_soc_register_card()
asoc: platform pcm constructor failed
asoc: can't create pcm HiFi :-12
asoc: failed to instantiate card PhyCORE-ac97-audio: -12
mx3fb configured for a 640x480 display:
soc-audio soc-audio: ASoC machine PhyCORE-ac97-audio should use
asoc: wm9712-hifi <-> imx-ssi.0 mapping ok
