[PATCH 5/9] ALSA: msnd: constify snd_pcm_ops structures

From: Arvind Yadav
Date: Fri Aug 11 2017 - 07:58:58 EST


snd_pcm_ops are not supposed to change at runtime. All functions
working with snd_pcm_ops provided by <sound/pcm.h> work with
const snd_pcm_ops. So mark the non-const structs as const.
