Can you move this to a PCI-layer helper, e.g. something like:

int pci_irq_get_node(struct pci_dev *dev, unsigned vec)
{
	const struct cpumask *mask = pci_irq_get_affinity(dev), i);
	if (mask)
		return local_memory_node(cpu_to_node(cpumask_first(mask)));
	return dev_to_node(&dev->dev);
}

Otherwise this looks fine.
