From 3d2a366190778f30a2f10b5edaf32bcb236840fd Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Fri, 24 Jan 2014 11:50:48 -0700 Subject: x86/PCI: Use pcibios_scan_root() instead of pci_scan_bus_on_node() pcibios_scan_root() looks up the bus's NUMA node, then calls pci_scan_bus_on_node(). This uses pcibios_scan_root() directly and drops the node lookup in the callers. Signed-off-by: Bjorn Helgaas Acked-by: Rafael J.
