ALSA: ac97: Treat snd_ac97_bus_ops as const
This is a preliminary patch to allow const for snd_ac97_bus_ops definitions in each driver's code. The ops reference is read-only, hence it can be declared as const for further optimization. There should be no functional changes by this patch. Link: https://lore.kernel.org/r/20200103081714.9560-23-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
