Subject: ALSA: usb-audio: Add support for Steinberg UR22 USB interface

From: Vlad Catoi <vladcatoi@xxxxxxxxx>

commit f0b127fbfdc8756eba7437ab668f3169280bd358 upstream.

Adding support for Steinberg UR22 USB interface via quirks table patch

See Ubuntu bug report:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1317244
Also see threads:
http://linux-audio.4202.n7.nabble.com/Support-for-Steinberg-UR22-Yamaha-USB-chipset-0499-1509-tc82888.html#a82917
http://www.steinberg.net/forums/viewtopic.php?t=62290

Tested by at least 4 people judging by the threads.
Did not test MIDI interface, but audio output and capture both are
functional. Built 3.17 kernel with this driver on Ubuntu 14.04 & tested with mpg123
Patch applied to 3.13 Ubuntu kernel works well enough for daily use.
