Subject: [PATCH net-next 21/46] can: janz-ican3: use DEVICE_ATTR_RO/RW() helper macro
Date: Mon, 26 Jul 2021 16:11:19 +0200	[thread overview]
Message-ID: <20210726141144.862529-22-mkl@pengutronix.de> (raw)
In-Reply-To: <20210726141144.862529-1-mkl@pengutronix.de>

From: Zhen Lei <thunder.leizhen@huawei.com>

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