The Linux Device Driver Model allows a physical device to be handled
by only a single driver. But at present, both shpchp and portdrv_pci
claim PCI_CLASS_BRIDGE_PCI. This cause problems, such as the wrong
shutdown seq. This series keeps shpchp driver away from pcie port device.

V1 -> V2:
implement the checking in the process of matching, instead of probing,
which is too late.

Pingfan Liu (2):
  pci: introduce an extra method for matching in pci_driver
  pci/shpchp: no claim on pcie port device
