PCIe definitely allows for BARs to be allocated to 0, so this is more or
less "the right thing". I really just wanted to make everyone aware that
I've run into issues with BARs actually located at address 0 in generic
PCI code in Linux ;).
So I don't think you really need my ack, as you definitely don't have a
nack from my side.
