Actually this should not be an error and the message is supposed to say:

	Unable to setup DMA, falling back to PIO

So IMHO this should be downgraded from dev_err to dev_info and reworded.
Maybe even try DMA-setup on devices where it is known to fail and don't
emit a message on -ENODEV at all.

Best regards
Uwe
