ALSA: info: Make snd_info_entry_ops as const
The reference to snd_info_entry_ops is rather read-only, so declare it as a const pointer. This allows a bit more optimization. There should be no functional changes by this patch. Link: https://lore.kernel.org/r/20200103081714.9560-29-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
