Merge tag 'pci-v4.6-fixes-3' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci
Pull PCI fixes from Bjorn Helgaas:
"Since v4.5, we've WARNed during resume if a PCI device, including a
Thunderbolt device, was added while we were suspended. A change we
merged for v4.6-rc1 turned that warning into a system hang. These
enumeration patches from Lukas Wunner fix this issue:
- Fix BUG on device attach failure
- Do not treat EPROBE_DEFER as device attach failure"
