Subject: [PATCH v2 23/29] xen/PCI: use pci_create_root_bus() instead of pci_scan_bus_parented()
Date: Thu, 13 Oct 2011 22:29:04 -0600 [thread overview]
Message-ID: <20111014042904.23504.36507.stgit@bhelgaas.mtv.corp.google.com> (raw)
In-Reply-To: <20111014042142.23504.70417.stgit@bhelgaas.mtv.corp.google.com>
No functional change here; just converting from the deprecated
pci_scan_bus_parented() to pci_create_root_bus().
I don't see that Xen ever updates the root bus resources, but in
general, the default resources (ioport_resource and iomem_resource)
installed by pci_create_bus() are incorrect.
