Subject: ASoC: txx9: constify snd_pcm_ops structures
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=5144468efb076b1859477de19257dd7ec9c24ed3;p=openwrt%2Fstaging%2Fblogic.git

ASoC: txx9: constify snd_pcm_ops structures

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