ALSA: aoa: Constify snd_kcontrol_new items
Most of snd_kcontrol_new definitions are read-only and passed as-is. Let's declare them as const for further optimization. There should be no functional changes by this patch. Link: https://lore.kernel.org/r/20200103081714.9560-33-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
