From: Adrian Bunk <bunk@...nel.org>

Subject: [2.6 patch] drivers/pci/: possible cleanups
This patch contains the following possible cleanups:
- make the following needlessly global function static:
- pci.c: pci_restore_bars()
- #if 0 the following unused global functions:
- rom.c: pci_map_rom_copy()
- rom.c: pci_remove_rom()
- remove the following unused EXPORT_SYMBOL's:
- pci-acpi.c: pci_osc_support_set
- proc.c: pci_proc_detach_bus
- remove the following unused EXPORT_SYMBOL_GPL's:
- bus.c: pci_walk_bus
- probe.c: pci_create_bus
- setup-res.c: pci_claim_resource
