Subject: [PATCH v4 05/30] PCI: Rename pci_scan_bus() to pci_scan_bus_legacy()
Date: Thu, 26 Feb 2015 16:11:59 +0800 [thread overview]
Message-ID: <1424938344-4017-6-git-send-email-wangyijing@huawei.com> (raw)
In-Reply-To: <1424938344-4017-1-git-send-email-wangyijing@huawei.com>
Pci_scan_bus() is called by legacy pci host drivers,
the legacy host drivers mean they use NULL as parent
device, use all IO/MEM as default resources. Rename
pci_scan_bus() to pci_scan_bus_legacy() for better
readability.
