Merge tag 'pci-v4.3-fixes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci

Pull PCI fix from Bjorn Helgaas:
 "Sorry for this last-minute update; it's been in -next for quite a
  while, but I forgot about it until I started getting ready for the
  merge window.

  It's small and fixes a way a user could cause a panic via sysfs, so I
  think it's worth getting it in v4.3.

  NUMA:
    - Prevent out of bounds access in sysfs numa_node override (Sasha Levin)"
