Forgot to mention, since ASoC DMAengine conversion is not going to happen any
time soon considering the amount of work involved, I suggest you respin this
patch on the common/edma code itself. That way we can keep suspend/resume
working on these platforms that use EDMA till the actual conversion takes place.

I suggest though to recreate the state based on existing datastructures instead
of allocating/saving additional memory.

Hope you're also in agreement with my comments on your original patch on what
needs to / need not be saved.

thanks,
