In the macro drm_mm_for_each_hole() 'hole_end' is provided as a container for 'hole_start + pos->hole_size', but is not utilised in this use-case. We cannot simply delete the variable, so here we tell the compiler that we're intentionally discarding the read value. Fixes the following W=1 kernel build warning(s): drivers/gpu/drm/selftests/test-drm_mm.c: In function ‘assert_no_holes’: drivers/gpu/drm/selftests/test-drm_mm.c:57:18: warning: variable ‘hole_end’ set but not used [-Wunused-but-set-variable] Cc: David Airlie <airlied@linux.ie> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: "Christian König" <christian.koenig@amd.com> Cc: Nirmoy Das <nirmoy.aiemd@gmail.com> Cc: dri-devel@lists.freedesktop.org Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20201116174112.1833368-28-lee.jones@linaro.org |
