Re: [PATCH] parisc: DMA API: return error instead of BUG_ON for dma ops on non dma devs

I've got a tree pending that removes DMA_ERROR_CODE, and it's been
in linux-next for a while.
While this won't compile-time conflict with this patch and will
basically revert the effect.
Can you please test the patch below and send it to Linus ASAP so that
I can send the pull request for the dma-mapping tree?
