ALSA: hdspm: More constifications
Apply const prefix to each possible place: the string arrays, the channel map tables and callers. Just for minor optimization and no functional changes. Link: https://lore.kernel.org/r/20200105144823.29547-20-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
