Subject: [PATCH v3 27/34] sh/PCI: convert to pci_scan_root_bus() for correct root bus resources
Date: Fri, 28 Oct 2011 16:27:48 -0600 [thread overview]
Message-ID: <20111028222748.30729.8949.stgit@bhelgaas.mtv.corp.google.com> (raw)
In-Reply-To: <20111028222432.30729.8431.stgit@bhelgaas.mtv.corp.google.com>
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.
