[PATCH] ASoC: fsl: Constify static snd_soc_ops
From: Rikard Falkeborn <hidden>
Date: 2021-09-21 01:40:41
Also in:
alsa-devel, linux-arm-kernel, lkml
Subsystem:
freescale soc sound drivers, sound, sound - soc layer / dynamic audio power management (asoc), the rest · Maintainers:
Shengjiu Wang, Xiubo Li, Jaroslav Kysela, Takashi Iwai, Liam Girdwood, Mark Brown, Linus Torvalds
These are only assigned to the ops field in the snd_soc_dai_link struct which is a pointer to const struct snd_soc_ops. Make them const to allow the compiler to put them in read-only memory.
