Merge tag 'pci-v4.15-fixes-1' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci

Pull PCI fixes from Bjorn Helgaas:

 - add a pci_get_domain_bus_and_slot() stub for the CONFIG_PCI=n case to
   avoid build breakage in the v4.16 merge window if a
   pci_get_bus_and_slot() -> pci_get_domain_bus_and_slot() patch gets
   merged before the PCI tree (Randy Dunlap)

 - fix an AMD boot regression in the 64bit BAR support added in v4.15
   (Christian König)

 - fix an R-Car use-after-free that causes a crash if no PCIe card is
   present (Geert Uytterhoeven)
