Subject: [PATCH 5/9] mfd: pcf50633: use DEVICE_ATTR_ADMIN_RO macro
Date: Wed, 2 Jun 2021 19:43:35 +0800	[thread overview]
Message-ID: <20210602114339.11223-6-thunder.leizhen@huawei.com> (raw)
In-Reply-To: <20210602114339.11223-1-thunder.leizhen@huawei.com>

Use DEVICE_ATTR_ADMIN_RO macro helper instead of plain DEVICE_ATTR, which
makes the code a bit shorter and easier to read.
