[ALSA] hda-codec - Fix possible array overflow
dac_nids arrays in each codec support code may have up to 5 items when assigned from the auto-configurator. Some codec codes have less numbers than the possible max. This patch defines the constant and fixes the array definitions. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>
