Subject: [PATCH part3 04/11] PCI: Use __pci_bus_size_bridges() directly in pci_assign_unassigned_bus_resources()
Date: Sun,  2 Sep 2012 14:52:14 -0700	[thread overview]
Message-ID: <1346622741-30799-5-git-send-email-yinghai@kernel.org> (raw)
In-Reply-To: <1346622741-30799-1-git-send-email-yinghai@kernel.org>

Now __pci_bus_size_bridges() will not include self bridge.
So we don't need to have our own version in
 pci_assign_unassigned_bus_resources anymore.
