3.13.11-ckt19 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Daniel Mack <daniel@zonque.org>

commit fcdcd1dec6d2c7b718385ec743ae5a9a233edad4 upstream.

The device complies to the UAC1 standard but hides that fact with
proprietary descriptors. The autodetect quirk for Roland devices
catches the audio interface but misses the MIDI part, so a specific
quirk is needed.
