Ok, I guess I didn't update all the patch descriptions properly...

This isn't correct anymore, as the dma_slave_descriptor struct turned
out not to be needed after all.

This isn't entirely correct either -- regular dma_async_tx_descriptors
are created, but one such descriptor can represent a whole scatterlist.

I'll update the changelog for the next round...
