There isn't a whole lot of value in this patch without another user.
I'll need to see the other patches that make use of this.
See the proposed Marvell PCIe driver and Tegra PCIe driver:

Alright, putting the functions into pci_ops doesn't sound like a very
good idea then. Or perhaps it would make sense for hardware where the
root complex and the MSI controller are handled by the same driver.

Is there actually hardware that supports this? I assumed that the MSI
controller would have to be tightly coupled to the PCI host bridge in
order to raise an interrupt when an MSI is received via PCI.
No, as long as it's guaranteed that the MSI
