From e2a7965ee07360c448ffa4eb3d5ccee01c42251e Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Fri, 28 Oct 2011 16:26:21 -0600 Subject: [PATCH] frv/PCI: convert to pci_scan_root_bus() for correct root bus resources Convert from pci_scan_bus() to pci_scan_root_bus() and remove root bus resource fixups. This fixes the problem of "early" and "header" quirks seeing incorrect root bus resources. Note that peer root buses are scanned with pci_scan_bus() (which is now deprecated), so they have the default ioport_resource and iomem_resource resources. This is unchanged from before, but these resources are incorrect, and I don't know how to discover the correct ones.
