Most systems' PCIe outbound map windows have non-zero physical addresses,
but the possibility of encountering zero increased with commit
700cafbb642b ("PCI: dwc: ep: Add bus_addr_base for outbound window").

I don't know what commit 700cafbb642b is.  It doesn't appear
upstream, and there's no subject line or patch match for
bus_addr_base.

Never mind, I see it's patch 5/7 of *this* series.  I looked at the
0/7 list, but missed it.

In any case, the commit ID will be different since we apply patches
from email, so the ID from your tree won't be useful.
