Hello Akhil P Oommen,
This is a semi-automatic email about new static checker warnings.
Commit 491fadb2b818 ("drm/msm/adreno: Move adreno_gpu_func to
catalogue") from Nov 18, 2025, leads to the following Smatch
complaint:
drivers/gpu/drm/msm/adreno/a3xx_gpu.c:530 a3xx_gpu_init() warn: variable
dereferenced before check 'pdev' (see line 525)
drivers/gpu/drm/msm/adreno/a4xx_gpu.c:642 a4xx_gpu_init() warn: variable
dereferenced before check 'pdev' (see line 637)
drivers/gpu/drm/msm/adreno/a2xx_gpu.c:503 a2xx_gpu_init() warn: variable
dereferenced before check 'pdev' (see line 500)
drivers/gpu/drm/msm/adreno/a3xx_gpu.c
524 struct platform_device *pdev = priv->gpu_pdev;
525 struct adreno_platform_config *config = pdev->dev.platform_data;
^^^^^^
The patch adds a new unchecked dereference.
526 struct icc_path *ocmem_icc_path;
527 struct icc_path *icc_path;
528 int ret;
529
530 if (!pdev) {
^^^^^
But the old code assumed pdev could be NULL.
531 DRM_DEV_ERROR(dev->dev, "no a3xx device\n");
532 ret = -ENXIO;
regards,
dan carpenter
