Subject: [PATCH 4.1 030/127] ALSA: usb-audio: Add sample rate inquiry quirk for AudioQuest DragonFly

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

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

From: Anssi Hannula <anssi.hannula@....fi>

commit 12a6116e66695a728bcb9616416c508ce9c051a1 upstream.

Avoid getting sample rate on AudioQuest DragonFly as it is unsupported
and causes noisy "cannot get freq at ep 0x1" messages when playback
starts.
