ALSA: snd-usb-audio: Skip un-parseable mixer units instead of erroring
Some interfaces reference endpoints which do not exists. To accomodate these, do not fail completely, but skip over them. This allows the Electrix Ebox-44 with earlier firmware to be detected and used for audio. Signed-off-by: Mark Hills <mark@pogo.org.uk> Signed-off-by: Takashi Iwai <tiwai@suse.de>
