[PATCH 4/7] ALSA: intel8x0: constify snd_pcm_ops structures
From: Arvind Yadav
Date: Thu Aug 10 2017 - 07:48:28 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.
