ALSA: hdsp: silence and underflow warning
I believe this probably cannot happen, as the code suggests. There would have to be an kcontrol->index.id which was zero, otherwise this would be prevented in snd_ctl_find_id(). But snd_BUG_ON() is just a WARN() or a no-op so static checkers complain that we keep on going with a negative offset. Let's just handle the error as well as printing a warning.
