From afa04880f46bbf84a90ac508c752b7ed0d76f8be Mon Sep 17 00:00:00 2001 From: Arvind Yadav Date: Thu, 10 Aug 2017 17:17:34 +0530 Subject: [PATCH] ALSA: echoaudio: constify snd_pcm_ops structures snd_pcm_ops are not supposed to change at runtime. All functions working with snd_pcm_ops provided by work with const snd_pcm_ops. So mark the non-const structs as const.
