I am also having problems with ASoC modules and deferred probing. This
patch seems to improve the a lot situation, though. Now it work most
of the time, but occasionally I get the warning below.

Not sure if this is directly related to the issue Russell have been
seeing. Guess it can be races in the Atmel ASoC drivers as well(?).

Looks the driver involved is out of tree since mpa1600_audio_probe
can't be found in -next or linux tree.

Also your problem should be related the driver and probably caused
by calling atmel_ssc_set_audio more than one time.

Thanks,
