3.8.13.7 -stable review patch. If anyone has any objections, please let me
know.
------------------
From: Felipe Balbi <ba...@ti.com>
commit cdcedd6981194e511cc206887db661d016069d68 upstream.
In case we fail our ->udc_start() callback, we
should be ready to accept another modprobe following
the failed one.
We had forgotten to clear dwc->gadget_driver back
to NULL and, because of that, we were preventing
gadget driver modprobe from being retried.
