The kernel oops below occurred due to incorrect\nerror handling flow when pci_setup_device() fails.\n\nAdd pci_iov_scan_device(), which handles virtfn allocation and setup and\ncleans up if pci_setup_device() fails, so pci_iov_add_virtfn() doesn't need\nto call pci_stop_and_remove_bus_device().  This prevents accessing\npartially initialized virtfn devices during removal.\n\n  BUG: kernel NULL pointer dereference, address: 00000000000000d0\n  RIP: 0010:device_del+0x3d/0x3d0\n  Call Trace:\n   pci_remove_bus_device+0x7c/0x100\n   pci_iov_add_virtfn+0xfa/0x200\n   sriov_enable+0x208/0x420\n   mlx5_core_sriov_configure+0x6a/0x160 [mlx5_core]\n   sriov_numvfs_store+0xae/0x1a0\n\n[bhelgaas: commit log, return ERR_PTR(-ENOMEM) directly]"
