I've been wondering about this part: since we need to pass the 'struct device' of
the dma engine (rather than the slave) into dma_map_single, what is the official
way to do that? Should the slave driver just rely on dma_chan->device->dev to
work correctly for the purpose of dma-mapping.h interfaces?
