From 46fbade05ca0784ca3c959bd7bf2aae7d81306c2 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Fri, 28 Oct 2011 16:28:08 -0600 Subject: x86/PCI: use pci_scan_bus() instead of pci_scan_bus_parented() This doesn't change any functionality, but it makes a subsequent patch slightly simpler. pci_scan_bus(NULL, ...) and pci_scan_bus_parented() are identical except that pci_scan_bus() also calls pci_bus_add_devices(): pci_scan_bus_parented pci_create_bus pci_scan_child_bus pci_scan_bus pci_create_bus pci_scan_child_bus pci_bus_add_devices All callers of pcibios_scan_root() call pci_bus_add_devices() explicitly, and we don't pass a parent device, so we might as well use pci_scan_bus().
