[PATCH 4.14 224/246] PCI: xgene: Remove leftover pci_scan_child_bus() call

[Greg Kroah-Hartman]

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Lorenzo Pieralisi <lorenzo.pieralisi@xxxxxxx>

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.

Fixes: 9af275be15f7 ("PCI: xgene: Convert PCI scan API to pci_scan_root_bus_bridge()")
