Subject: [PATCH -next] ASoC: codecs: lpass-rx-macro: constify static struct snd_soc_dai_ops
Date: Thu, 8 Apr 2021 14:26:50 +0800	[thread overview]
Message-ID: <20210408062650.803309-1-yebin10@huawei.com> (raw)

The snd_soc_dai_ops structures is only stored in the ops field of a
snd_soc_dai_driver structure, so make the snd_soc_dai_ops structure
const to allow the compiler to put it in read-only memory.
