ALSA: hda: Constify snd_device_ops definitions
Now we may declare const for snd_device_ops definitions, so let's do it for optimization. There should be no functional changes by this patch. Link: https://lore.kernel.org/r/20200103081714.9560-9-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
