From 1da7f0c570d7356f232aee6528ccf8b2dcd96dcf Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 3 Jan 2020 09:16:59 +0100 Subject: [PATCH] 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.
