vgaarb: a NULL bridge is acceptable for root devices.
I assumed all PCI buses had a bridge, but playing with qemu recently, I discovered vgaarb bug where it wasn't detecting both devices shared a bridge at the root level. Don't check for NULL, if two buses have a NULL bridge, assume they share the root bus. Acked-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Dave Airlie <airlied@redhat.com>
