Yes, thank you a lot for your review!

While I have your attention - with these two patches we stop building
dummy_dma_ops for most common configs.  Do you think we need additional
safeguards for this case?  My idea would be to remove them and force the
bus_dma_mask to zero where we currently set the dummy ops, but I could
use a little reality check for that idea.
