But pci_dev->irq is populated correctly, so vp_find_vqs_intx() would succeed if we called it - which is what the code used to do. I think this happens because pci_dev->pin is not populated in pci_assign_irq(). I would absolutely believe this is bug in our PCI code, but I think it may also affect other platforms that use of_irq_parse_and_map_pci(). cheers
