From 4c1e9df7264567617ba2ed620338dfcef0618c39 Mon Sep 17 00:00:00 2001 From: Dmitry Baryshkov Date: Mon, 2 May 2022 11:24:20 +0300 Subject: [PATCH] drm/msm/dpu: don't access mode pointer before it is set Move the initializer for the mode variable to the declaration point to remove unitialized variable access from the DEBUG_DPU macro. This fixes the following warning: drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_wb.c:250:37: note: initialize the variable 'mode' to silence this warning Fixes: d7d0e73f7de3 ("drm/msm/dpu: introduce the dpu_encoder_phys_* for writeback") Reported-by: kernel test robot Signed-off-by: Dmitry Baryshkov Reviewed-by: Abhinav Kumar Patchwork: https://patchwork.freedesktop.org/patch/484346/ Link: https://lore.kernel.org/r/20220502082420.48409-1-dmitry.baryshkov@linaro.org Signed-off-by: Dmitry Baryshkov --- drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_wb.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_wb.c b/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_wb.c index f4a7971..4829d1c 100644 --- a/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_wb.c +++ b/drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_wb.c @@ -247,7 +247,7 @@ static int dpu_encoder_phys_wb_atomic_check( struct drm_connector_state *conn_state) { struct drm_framebuffer *fb; - const struct drm_display_mode *mode; + const struct drm_display_mode *mode = &crtc_state->mode; DPU_DEBUG("[atomic_check:%d, \"%s\",%d,%d]\n", phys_enc->wb_idx, mode->name, mode->hdisplay, mode->vdisplay); @@ -256,7 +256,6 @@ static int dpu_encoder_phys_wb_atomic_check( return 0; fb = conn_state->writeback_job->fb; - mode = &crtc_state->mode; if (!conn_state || !conn_state->connector) { DPU_ERROR("invalid connector state\n"); -- 2.7.4
