Subject: [PATCH v10 25/29] PCI/designware: Use pci_scan_root_bus() for simplicity
Date: Tue, 21 Apr 2015 19:34:44 +0800 [thread overview]
Message-ID: <1429616088-10249-26-git-send-email-wangyijing@huawei.com> (raw)
In-Reply-To: <1429616088-10249-1-git-send-email-wangyijing@huawei.com>
Use pci_scan_root_bus() instead of pci_create_root_bus() +
pci_scan_child_bus() for simplicity.
