Subject: [PATCH 36/93] ALSA: usb-audio: fix Roland/Cakewalk UM-3G support

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

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

From: Clemens Ladisch <clemens@...isch.de>

commit a0c6d309c6df14655f9962f666d1da96318b0b7c upstream.

Commit 927c9423dd5f2d1c0b93d5e694ab84b4a5559713 (ALSA: usb-audio: add
Edirol UM-3G support) used a wrong quirk type, which would make the
driver refuse to attach with the error message "MIDIStreaming interface
descriptor not found".
