Subject: [PATCH -next] ASoC: rt1019: constify static struct snd_soc_dai_ops
Date:   Thu, 8 Apr 2021 14:27:01 +0800
Message-ID: <20210408062701.803865-1-yebin10@huawei.com>
MIME-Version: 1.0
Content-Type:   text/plain; charset=US-ASCII
Content-Transfer-Encoding: 7BIT
Precedence: bulk

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.
