Merge tag 'pci-v4.13-fixes-3' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci
Pull PCI fix from Bjorn Helgaas: "Remove needlessly alarming MSI affinity warning (this is not actually a bug fix, but the warning prompts unnecessary bug reports)" * tag 'pci-v4.13-fixes-3' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci: PCI/MSI: Don't warn when irq_create_affinity_masks() returns NULL
