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
  snd_soc_register_card()
  asoc: wm9712-hifi <-> imx-ssi.0 mapping ok
