powerpc and sparc are using that.

Ben,

in drivers/pci/probe.c::pci_scan_device() there is

        pci_set_of_node(dev);

        if (pci_setup_device(dev)) {
                kfree(dev);
                return NULL;
        }

so if pci_setup_device fails, there is one dev reference is not release.

please check you can just move down pci_set_of_node down after that
failing path, like


        if (pci_setup_device(dev)) {
                kfree(dev);
                return NULL;
        }

        pci_set_of_node(dev);
