Subject: [PATCH -next] ASoC: rk817: Constify static struct snd_soc_dai_ops
Date: Wed, 2 Jun 2021 11:36:43 +0000	[thread overview]
Message-ID: <20210602113643.3037374-1-weiyongjun1@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.
