[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.
