PCI: read revision ID by default
Currently there are 97 occurrences where drivers need the pci revision ID. We can do this once for all devices. Even the pci subsystem needs the revision several times for quirks. The extra u8 member pads out nicely in the pci_dev struct. Signed-off-by: Auke Kok <auke-jan.h.kok@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
