I would prefer if this was expanded to a proper sentence, and I really
like the second part of the commit message to be included in the change.
So something like:

			dev_err(dev, "failed to remap %#x bytes from %#x\n",
				att->size, att->sa);


And similarly below if mapping a memory-region fails.

Thanks,
