Pull PCI fixes from Bjorn Helgaas:
 "These are fixes for an SHPCHP hotplug regression, a "wait for pending
  transaction" problem (used in device reset paths), and an email
  address update.

  PCI device hotplug:

  Miscellaneous:
    - Fix pci_wait_for_pending_transaction() (Gavin Shan)
    - Update email address (Ben Hutchings)"
