From 97f41002945fd9c55e8b80c654ea34fd434250e7 Mon Sep 17 00:00:00 2001 From: Zhen Lei Date: Thu, 3 Jun 2021 20:30:41 +0800 Subject: mtd: mtdpart: use DEVICE_ATTR_RO() helper macro Use DEVICE_ATTR_RO() helper macro instead of plain DEVICE_ATTR(), which makes the code a bit shorter and easier to read.
