[PATCH] PCI: Reduce nr of ptr derefs in drivers/pci/hotplug/rpaphp_pci.c
Here's a small patch to reduce the nr. of pointer dereferences in drivers/pci/hotplug/rpaphp_pci.c Benefits: - micro speed optimization due to fewer pointer derefs - generated code should be slightly smaller - better readability note: due to lack of both hardware and cross-compile tools this patch is, unfortunately, completely untested.
