From: Bjorn Helgaas Date: Fri, 28 Oct 2011 22:26:16 +0000 (-0600) Subject: arm/PCI: convert to pci_scan_root_bus() for correct root bus resources X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=37d15909ff6bf6e97e1d4447efa7f1a19e7a508e;p=linux-beck.git arm/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.
