Sorry, I don't know why but I was thinking that PCM module will
not load when we have a DMA platform but indeed it will load the
module because of the dependencies, even though the register
function will never be called. Without this I don't really have
anything against the patch.

What do you think Mark? If you want to keep the PCM as a module
then we will need to abstract this more, by reducing the
dependencies.
