Andreas Noever 7cf009d054 PCI: pciehp: Prevent NULL dereference during probe
commit bceee4a97e upstream.

pciehp assumes that dev->subordinate, the struct pci_bus for a bridge's
secondary bus, exists.  But we do not create that bus if we run out of bus
numbers during enumeration.  This leads to a NULL dereference in
init_slot() (and other places).

Change pciehp_probe() to return -ENODEV when no secondary bus is present.
