[alsa-devel] [PATCH 04/14] ASoC: fsl: constify snd_soc_dai_ops structures

Arvind Yadav arvind.yadav.cs at gmail.com
Fri Aug 18 14:06:01 CEST 2017


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