commit 94b9d290b753cbbc87971ee134511245f5872a83 upstream.
The changes in commit 9af275be15f7 ("PCI: xgene: Convert PCI scan API to pci_scan_root_bus_bridge()") converted the xgene PCI host driver to the new pci_scan_root_bus_bridge() bus scanning API but erroneously left the existing pci_scan_child_bus() call in place which resulted in duplicate PCI bus enumerations.
Remove the leftover pci_scan_child_bus() call to properly complete the API conversion.
