From b30df293fd3bb737a6ea54c950f00c6aee31adff Mon Sep 17 00:00:00 2001 From: Bernard Zhao Date: Thu, 7 May 2020 02:13:05 -0700 Subject: [PATCH] drm/amd/amdgpu: cleanup coding style a bit MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit There is DEVICE_ATTR mechanism in separate attribute define. So this change is to use attr array, also use sysfs_create_files in init function & sysfs_remove_files in fini function. This maybe make the code a bit readable.
