From de4b2f76d69673cea08be952dcb4df2f4c81c6e3 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Fri, 28 Oct 2011 16:25:55 -0600 Subject: PCI: convert pci_scan_bus() to use pci_create_root_bus() I plan to deprecate pci_scan_bus_parented(), so use pci_create_root_bus() directly instead. pci_scan_bus() itself will be removed as soon as all callers are gone, so this is just an interim step. v2: export pci_scan_bus Signed-off-by: Bjorn Helgaas Signed-off-by: Jesse Barnes --- drivers/pci/probe.c | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) (limited to 'drivers/pci') diff --git a/drivers/pci/probe.c b/drivers/pci/probe.c index 7fc7e14118cc..d09644b52d1c 100644 --- a/drivers/pci/probe.c +++ b/drivers/pci/probe.c @@ -1649,6 +1649,25 @@ struct pci_bus * __devinit pci_scan_bus_parented(struct device *parent, } EXPORT_SYMBOL(pci_scan_bus_parented); +struct pci_bus * __devinit pci_scan_bus(int bus, struct pci_ops *ops, + void *sysdata) +{ + LIST_HEAD(resources); + struct pci_bus *b; + + pci_add_resource(&resources, &ioport_resource); + pci_add_resource(&resources, &iomem_resource); + b = pci_create_root_bus(NULL, bus, ops, sysdata, &resources); + if (b) { + b->subordinate = pci_scan_child_bus(b); + pci_bus_add_devices(b); + } else { + pci_free_resource_list(&resources); + } + return b; +} +EXPORT_SYMBOL(pci_scan_bus); + #ifdef CONFIG_HOTPLUG /** * pci_rescan_bus - scan a PCI bus for devices. -- cgit v1.2.3
