Hi Greg

One more xhci patch for usb-linus that hopefully can make 4.4.

An issue in xhci usb2 port resume code was found that sometimes prevents
xhci usb2 roothub runtime suspend, always returning -EBUSY,
leaving a kworker thread spinning in rpm_suspend.

Mathias Nyman (1):
  xhci: fix usb2 resume timing and races.
