If we don't have an interrupt-map on a PCI controller, why don't
we
instead log a message regarding that being missing, and give up
early?

Why ? It's legit to not support LSIs.

Sure; I had envisioned a message like:

	pr_info("%s: no interrupt-map, INTx interrupts not possible\n",
		pci_controller_name);

... Which tells the user exaclty what we know, and doesn't imply
either
an error or the actual absence of HW support.

Works for me.

Cheers,
Ben.
