From 02f40f82c440b70cce26ac4edd0aaf7069734af4 Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Thu, 5 Nov 2020 14:45:16 +0000 Subject: [PATCH] gpu: drm: amd: amdgpu: amdgpu: Mark global variables as __maybe_unused MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit These 3 variables are used in *some* sourcefiles which include amdgpu.h, but not *all*. This leads to a flurry of build warnings. Fixes the following W=1 kernel build warning(s): from drivers/gpu/drm/amd/amdgpu/amdgpu.h:67, drivers/gpu/drm/amd/amdgpu/amdgpu.h:198:19: warning: ‘no_system_mem_limit’ defined but not used [-Wunused-const-variable=] drivers/gpu/drm/amd/amdgpu/amdgpu.h:197:19: warning: ‘debug_evictions’ defined but not used [-Wunused-const-variable=] drivers/gpu/drm/amd/amdgpu/amdgpu.h:196:18: warning: ‘sched_policy’ defined but not used [-Wunused-const-variable=] NB: Repeats ~650 times - snipped for brevity.
