The xhci retaining bogus hardware states cause usb disconnect devices
connected before hibernation(s4) and refer to the commit '547d55fa83
("usb: ohci-platform: fix usb disconnect issue after s4")' which set
flag "hibernated" as true when resume-from-hibernation and that the
drivers will reset the hardware to get rid of any existing state and
make sure resume from hibernation re-enumerates everything for xhci.

Please fix this up and add a proper Fixes: line and if needed a cc:
stable line.

Sorry, I misunderstood your meaning earlier. This patch is not meant to
fix the bugs in the previous commit id. Actually, it was to fix xhci
issue that refer to repair of ohci (commit id "f3d478858bec4").
>>>

Do I need to add Cc about stable kernel for the above situation?
Thanks,
