ALSA: hda - Terminate the recursive connection search properly
The recursive search of widget connections in snd_hda_get_conn_index() must be terminated at the pin and the audio-out widgets. Otherwise you'll get "too deep connection" warnings unnecessarily. Reported-by: Francis Moreau <francis.moro@gmail.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
