From 89a74ecccd1f78e51faf6287e5c0e93a92ac096e Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas <bjorn.helgaas@hp.com> Date: Tue, 23 Feb 2010 10:24:31 -0700 Subject: PCI: add pci_bus_for_each_resource(), remove direct bus->resource[] refs No functional change; this converts loops that iterate from 0 to PCI_BUS_NUM_RESOURCES through pci_bus resource[] table to use the pci_bus_for_each_resource() iterator instead. This doesn't change the way resources are stored; it merely removes dependencies on the fact that they're in a table.
