Ok, perfect, thanks for taking a closer look as well.

Right, I think I considered doing this at some point as well, not sure
why I left it in for the version I posted. Passing the IORESOURCE_DMA
values is clearly wrong by itself and needs to be removed, though
it's not obvious what the correct way of requesting the DMA channel
is for this driver either, without a DT binding or users.
