Sorry, I reviewed this patch before but forgot to ack it, so here it is:
Acked-by: Catalin Marinas <catalin.marinas-5wv7dgnIgG8@public.gmane.org>
(and I'm fined for the arm64 patches here to go in via the iommu tree)
I assume part of this patch will disappear at some point when the device
probing order is sorted.
