If you notice yourself writing "also, the patch does this" in the patch
description, it's usually a sign that the patch needs to be split =).

That's perhaps not so important when a patch only deals with one
subsystem or one file, but when the patch changes arch, video and audio
drivers at the same time I would like to have the patches as simple as

Here I suggest you handle the DMA port change in a separate patch.
