ALSA: hda - Treat zero connection as non-error
The zero-length connection list happens so often on Haswell HDMI, and it results in warning messages like ALSA: hda_codec: invalid CONNECT_LIST verb 5[1]:0 at each time the codec resumes from the power-save, which is fairly annoying. Since this is no real error, make it shown only in the verbose debug mode. Signed-off-by: Takashi Iwai <tiwai@suse.de>
