From mboxrd@z Thu Jan 1 00:00:00 1970 From: wangyijing@huawei.com (Yijing Wang) Date: Tue, 28 Apr 2015 15:01:38 +0800 Subject: [PATCH Part1 v11 4/5] PCI: xgene: Use pci_scan_root_bus() instead of pci_create_root_bus() In-Reply-To: <1430204499-19571-1-git-send-email-wangyijing@huawei.com> References: <1430204499-19571-1-git-send-email-wangyijing@huawei.com> Message-ID: <1430204499-19571-5-git-send-email-wangyijing@huawei.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
