Subject: [PATCH Part1 v11 4/5] PCI: xgene: Use pci_scan_root_bus() instead of pci_create_root_bus()
Date: Tue, 28 Apr 2015 15:01:38 +0800 [thread overview]
Message-ID: <1430204499-19571-5-git-send-email-wangyijing@huawei.com> (raw)
In-Reply-To: <1430204499-19571-1-git-send-email-wangyijing@huawei.com>
Pci_bus_add_devices() was ripped out of pci_scan_root_bus().
Now pci_scan_root_bus() == pci_create_root_bus() +
pci_scan_child_bus() if busn resource is supplied.
Xgene added the busn resource to resources list
in of_pci_get_host_bridge_resources(). So it should be safe
to use pci_scan_root_bus() instead.
