Adding a soc-audio sound driver internally uses snd_soc_register_device, which tries to bind it with the codec. The adding of the driver is deferred because the codec driver is not loaded.

This patch changes the order of registration. The codec driver is there before the ac97 driver, so the snd_soc_register_device call is successfull.

You shouldn't be using soc-audio in the first place...
