Subject: [PATCH 3.14 16/88] ALSA: usb-audio: fix BOSS ME-25 MIDI regression

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

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

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

commit 53da5ebfef66ea6e478ad9c6add3781472b79475 upstream.

The BOSS ME-25 turns out not to have any useful descriptors in its MIDI
interface, so its needs a quirk entry after all.

Reported-and-tested-by: Kees van Veen <kees.vanveen@...il.com>
