Subject: [PATCH v2 28/29] sh/PCI: convert to pci_scan_root_bus() for correct root bus resources
Date: Thu, 13 Oct 2011 22:29:30 -0600	[thread overview]
Message-ID: <20111014042930.23504.60734.stgit@bhelgaas.mtv.corp.google.com> (raw)
In-Reply-To: <20111014042142.23504.70417.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.
