I'd rather put an explicit error bail-out, i.e.
diff --git a/sound/usb/mixer.c b/sound/usb/mixer.c index 91bc8f18791e..296a63a9d09c 100644 --- a/sound/usb/mixer.c +++ b/sound/usb/mixer.c @@ -204,6 +204,10 @@ static int snd_usb_copy_string_desc(struct mixer_build *state, int index, char *buf, int maxlen) { int len = usb_string(state->chip->dev, index, buf, maxlen - 1);

return len;

I will resend v2 patch with your suggestion.
