Ah, right. I see your point.

I don't actually see why pci_add_dma_alias() should be exported at all.

I suspect the best approach is for Jacek to add a second patch in this
series, adding the required quirk to drivers/pci/quirks.c for the
device in question, and then resubmit them to you when Linus releases
4.5-rc1.

This is completely independent of any native driver for the device, of
course.
