ASoC: txx9: constify snd_pcm_ops structures

ArvindYadavCs · broonie · commit 5144468efb07 · 2017-08-14T17:21:25.000+01:00
snd_pcm_ops are not supposed to change at runtime. All functions
working with snd_pcm_ops provided by &lt;sound/soc.h&gt; work with
const snd_pcm_ops. So mark the non-const structs as const.
