Hello Dmitry Baryshkov,
This is a semi-automatic email about new static checker warnings.
Commit 4f89cf40d01e ("drm/msm: bail out late_init_minor() if it is
not a GPU device") from Jul 5, 2025, leads to the following Smatch
complaint:
drivers/gpu/drm/msm/msm_debugfs.c:332 late_init_minor()
warn: variable dereferenced before check 'minor' (see line 328)
drivers/gpu/drm/msm/msm_debugfs.c
327 {
328 struct drm_device *dev = minor->dev;
^^^^^^^
The patch adds a dereference
329 struct msm_drm_private *priv = dev->dev_private;
330 int ret;
331
332 if (!minor)
^^^^^^
But the older code assumes the minor can be NULL
333 return 0;
334
regards,
dan carpenter
