Then the\nnext thing pci_qdev_realize() does is call pcie_sriov_register_device(),\nwhich returns the appropriate error.\n\nCc: qemu-stable@nongnu.org\nFixes: d0c280d3fac6 (\u0027pcie_sriov: Make a PCI device with user-created VF ARI-capable\u0027)\nSigned-off-by: Kevin Wolf \u003ckwolf@redhat.com\u003e\nReviewed-by: Stefan Hajnoczi \u003cstefanha@redhat.com\u003e\nReviewed-by: Michael S.
