ASoC: zx-i2s: constify snd_soc_dai_ops structure

GustavoARSilva · broonie · commit 45d059a33aa4 · 2017-07-17T16:18:15.000+01:00
This structure is only stored in the ops field of a snd_soc_dai_driver
structure. That field is declared const, so snd_soc_dai_ops structures
that have this property can be declared as const also.
