Subject: [PATCH -next] ASoC: cs42l52: use DEVICE_ATTR_WO macro
Date:   Mon, 24 May 2021 19:42:39 +0800
Message-ID: <20210524114239.7960-1-yuehaibing@huawei.com>
MIME-Version: 1.0
Content-Type: text/plain
Precedence: bulk

Use DEVICE_ATTR_WO() helper instead of plain DEVICE_ATTR(),
which makes the code a bit shorter and easier to read.
