Subject: [PATCH 1/1] can: at91_can: use DEVICE_ATTR_RW() helper macro
Date:   Thu, 3 Jun 2021 18:02:33 +0800
Message-ID: <20210603100233.11877-1-thunder.leizhen@huawei.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 7BIT
Content-Type:   text/plain; charset=US-ASCII
Precedence: bulk

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