ALSA: dummy: Constify snd_pcm_ops definitions
The snd_pcm_ops items defined in snd-dummy driver can be gracefully declared as const. Let's mark them for further optimization. There should be no functional changes by this patch. Link: https://lore.kernel.org/r/20200103081714.9560-44-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
