From fc2798502f860b18f3c7121e4dc659d3d9d28d74 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Mon, 9 Dec 2013 22:54:40 -0800 Subject: PCI: Convert pcibios_resource_to_bus() to take a pci_bus, not a pci_dev These interfaces: pcibios_resource_to_bus(struct pci_dev *dev, *bus_region, *resource) pcibios_bus_to_resource(struct pci_dev *dev, *resource, *bus_region) took a pci_dev, but they really depend only on the pci_bus. And we want to use them in resource allocation paths where we have the bus but not a device, so this patch converts them to take the pci_bus instead of the pci_dev: pcibios_resource_to_bus(struct pci_bus *bus, *bus_region, *resource) pcibios_bus_to_resource(struct pci_bus *bus, *resource, *bus_region) In fact, with standard PCI-PCI bridges, they only depend on the host bridge, because that's the only place address translation occurs, but we aren't going that far yet.
