From ae624a38be37e1a3127d5fa32c996e09974bb88d Mon Sep 17 00:00:00 2001 From: YueHaibing Date: Mon, 24 May 2021 19:55:06 +0800 Subject: [PATCH] ASoC: Intel: Skylake: 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.
