Subject: ALSA: usb-audio: Add sample rate inquiry quirk for AudioQuest DragonFly
From: Anssi Hannula <anssi.hannula@xxxxxx>
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.
