Alan Stern 6ec4beb5c7 USB: new flag for resume-from-hibernation
This patch (as1237) changes the way the PCI host controller drivers
avoid retaining bogus hardware states during resume-from-hibernation.
Previously we had reset the hardware as part of preparing to reinstate
the memory image.  But we can do better now with the new PM framework,
since we know exactly which resume operations are from hibernation.

The pci_resume method is changed to accept a flag indicating whether
the system is resuming from hibernation.  When this flag is set, the
drivers will reset the hardware to get rid of any existing state.

Similarly, the pci_suspend method is changed to remove the
pm_message_t argument.  It's no longer needed, since no special action
has to be taken when preparing to reinstate the memory image.
