Luis Henriques - July 30, 2013, 9:31 a.m. -stable review patch.  If anyone has any objections, please let me know.


From: Felipe Balbi <>

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.
