Subject: [PATCH] PCI: set correct value for iov device before device
Since device registering is put into pci_device_add(), it must set value of
Virtual Function device's member before the pci_dev is put to device tree. Or
some relevant subsystem of driver model such as xen will report a incorrect
IOV device to Xen hypervior.
