Subject: [PATCH] ALSA: dummy: Constify snd_pcm_ops definitions
Git-commit: 1da7f0c570d7356f232aee6528ccf8b2dcd96dcf
Patch-mainline: v5.6-rc1
References: jsc#SLE-16518

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.
