Indeed, there is no need to describe and handle how DMA may or may not be translated for I2C/SPI/USB/etc. because they are not DMA-capable buses (in those cases the relevant bus *controller* often does DMA, but it does that for itself as the platform/PCI/etc. device it is). Note that I have a series pending[1] that will make this patch a whole lot simpler. Thanks, Robin.
