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.
