[PATCH] PCI Hotplug/powerpc: more removal of duplicated code
The RPAPHP code contains two routines that appear to be gratuitous copies of very similar pci code. In particular, rpaphp_claim_resource ~~ pci_claim_resource (there is a minor, non-functional difference) rpadlpar_claim_one_bus == pcibios_claim_one_bus (the code is identical) This patch removes the rpaphp versions of the code.
