Hi Greg

A few xhci fixes for usb-linus.

USB3 devices aren't visible immediately after xHC reset, so don't
stop polling the roothub and suspend too early after xHC reset.

Also Revert the port poweroff patch due to regression,
and fix a null pointer issue for xHC hosts with just one roothub.

-Mathias

Mathias Nyman (3):
  xhci: Fix null pointer dereference in remove if xHC has only one
    roothub
  xhci: Add grace period after xHC start to prevent premature runtime
    suspend.
  Revert "xhci: turn off port power in shutdown"
