3.16.74-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Takashi Iwai <tiwai@xxxxxxx>
commit 328e9f6973be2ee67862cb17bf6c0c5c5918cd72 upstream.
The error from snd_usb_mixer_apply_create_quirk() is ignored in the
current usb-audio driver code, which will continue the probing even
after the error. Let's take it more serious.
Fixes: 7b1eda223deb ("ALSA: usb-mixer: factor out quirks")
