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)"
