- fix use-before-set error in ibmphp (Dan Carpenter)

  - fix pciehp timeouts caused by Command Completed errata (Bjorn Helgaas)

  - fix refcounting in pnv_php hotplug (Julia Lawall)

  - clear pciehp Presence Detect and Data Link Layer Status Changed on
    resume so we don't miss hotplug events (Mika Westerberg)

  - only request pciehp control if we support it, so platform can use ACPI
    hotplug otherwise (Mika Westerberg)
