From c4e06576282c5f91549b344fd0f516c421332b68 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Fri, 28 Oct 2011 16:27:07 -0600 Subject: parisc/PCI: dino: use pci_create_bus() instead of pci_scan_bus_parented() No functional change here; just converting from pci_scan_bus_parented() to pci_create_bus() to make a future patch simpler.
