From 56466f653cb59a8f46e991ad1e285f43afdca7d4 Mon Sep 17 00:00:00 2001 From: Dan Carpenter <dan.carpenter@linaro.org> Date: Fri, 13 Oct 2023 11:25:15 +0300 Subject: [PATCH] drm/msm: remove unnecessary NULL check MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This NULL check was required when it was added, but we shuffled the code around and now it's not. The inconsistent NULL checking triggers a Smatch warning: drivers/gpu/drm/msm/disp/mdp5/mdp5_kms.c:847 mdp5_init() warn: variable dereferenced before check 'mdp5_kms' (see line 782) Fixes: 1f50db2f3e1e ("drm/msm/mdp5: move resource allocation to the _probe function") Signed-off-by: Dan Carpenter <dan.carpenter@linaro.org> Reviewed-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Reviewed-by: Abhinav Kumar <quic_abhinavk@quicinc.com> Patchwork: https://patchwork.freedesktop.org/patch/562559/ Link: https://lore.kernel.org/r/ZSj+6/J6YsoSpLak@kadam Signed-off-by: Abhinav Kumar <quic_abhinavk@quicinc.com> --- drivers/gpu/drm/msm/disp/mdp5/mdp5_kms.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/drivers/gpu/drm/msm/disp/mdp5/mdp5_kms.c b/drivers/gpu/drm/msm/disp/mdp5/mdp5_kms.c index a28fbcd096842..40cda31c8ed1d 100644 --- a/drivers/gpu/drm/msm/disp/mdp5/mdp5_kms.c +++ b/drivers/gpu/drm/msm/disp/mdp5/mdp5_kms.c @@ -844,8 +844,7 @@ static int mdp5_init(struct platform_device *pdev, struct drm_device *dev) return 0; fail: - if (mdp5_kms) - mdp5_destroy(mdp5_kms); + mdp5_destroy(mdp5_kms); return ret; } -- GitLab
