Up to 2.6.28 the ASoC framework was working on AT32AP7000 Atmel platform.
Now I try to recompile it on 2.6.31-rc8 and I get

Advance Linux Sound Architecture Driver Version 1.0.20.
No device for DAI atmel-ssc0
No device for DAI atmel-ssc1
No device for DAI atmel-ssc2

whereas the ssc devices are properly (as in 2.6.28) initialized
ssc ssc.0: Atmel SSC device at 0xffe1c00 (irq 10)
ssc ssc.1: Atmel SSC device at 0xffe2000 (irq 11)
ssc ssc.2: Atmel SSC device at 0xffe2400 (irq 12)

It looks that this message comes from snd_soc_register_dai in soc-core.c

if (!dai->dev)
         printk(KERN_WARNING "No device for DAI %s\n", dai->name);

it seems for some reason it thinks there is no device in dai->dev

Unless I'm mistaken, that is being called from
sound/soc/atmel/atmel_ssc_dai.c after some modifications done by
broonie on these files according to

Is there anything that can be done to rectify this?
