Subject: [PATCH -next] phy: phy-twl4030-usb: use DEVICE_ATTR_RO macro
Date: Thu, 20 May 2021 21:51:32 +0800	[thread overview]
Message-ID: <20210520135132.37628-1-yuehaibing@huawei.com> (raw)

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