[PATCH] ASoC: fsl: constify static snd_soc_dai_ops structs

From: Rikard Falkeborn
Date: Sat Feb 06 2021 - 18:00:36 EST


The only usage of these is to assign their address to the 'ops' field in
the snd_soc_dai_driver struct, which is a pointer to const. Make them
const to allow the compiler to put them in read-only memory.
