PCI: Add include guard to include/linux/pci_ids.h Adding an include guard frees the preprocessor from reparsing over 2600 #defines in the cases where pci_ids.h is somehow included more than once. This gives a tiny-but-measurable performance improvement when compiling such files. Signed-off-by: Rasmus Villemoes <linux@rasmusvillemoes.dk> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
