[PATCH] ASoC: amd: acp6x-pdm-dma: Constify static snd_soc_dai_ops

From: Rikard Falkeborn
Date: Sat Dec 04 2021 - 06:09:02 EST


The only usage of acp6x_pdm_dai_ops is to assign its address to the ops
field in the snd_soc_dai_driver struct, which is a pointer to const
snd_soc_dai_ops. Make it const to allow the compiler to put it in
read-only memory.
