Therefore call it in the pci_device_probe() function during the enable device code path so this assignment can be performed. This patch will do nothing on arches which do not set the irq mapping function pointers and is therefore currently a nop, however as support for these function pointers is added to arch specific code this will cause irq assignment to migrate to device enable time allowing the new code paths to be used.
