Subject: ALSA: usb-audio: Add quirks for M-Audio Fast Track C400/600
From: Takashi Iwai <tiwai@xxxxxxx>
commit 794814529384721ce8f4d34228dc599cc010353d upstream.
M-Audio Fast Track C400 and C600 devices (0763:2030 and 0763:2031,
respectively) seem requiring the explicit setup for the implicit
feedback mode. This patch adds the quirk entries for those.
