but this one especially I'd like to get into ASoC as soon as possible
since this one should be being used by other things.

I'm a bit concerned about anything actually using dma_dev since it
indicates that something is being worked around, it'd be a bit nicer to
print a warning when doing this to give people a hint that they might
not be doing the right thing if they use it (unless someone comes up
with a system that has a clear use case for it).
