From: YueHaibing Date: Mon, 24 May 2021 11:40:17 +0000 (+0800) Subject: ASoC: cs43130: Use DEVICE_ATTR_RO macro X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6405941e6884dac80f836acfc7ec52089ea6aa99;p=linux.git ASoC: cs43130: Use DEVICE_ATTR_RO macro Use DEVICE_ATTR_RO() helper instead of plain DEVICE_ATTR(), which makes the code a bit shorter and easier to read.
