Subject: [PATCH 2/9] mfd: ucb1x00-assabet: use DEVICE_ATTR_RO macro
Date: Wed, 2 Jun 2021 19:43:32 +0800 [thread overview]
Message-ID: <20210602114339.11223-3-thunder.leizhen@huawei.com> (raw)
In-Reply-To: <20210602114339.11223-1-thunder.leizhen@huawei.com>
Use DEVICE_ATTR_RO macro helper instead of plain DEVICE_ATTR, which makes
the code a bit shorter and easier to read.
Signed-off-by: Zhen Lei <thunder.leizhen@huawei.com>
