Hello Philippe CORNU,
This is a semi-automatic email about new static checker warnings.
The patch b706a25eaed0: "drm/stm: ltdc: add clut mode support" from
Oct 26, 2017, leads to the following Smatch complaint:
drivers/gpu/drm/stm/ltdc.c:395 ltdc_crtc_update_clut()
warn: variable dereferenced before check 'crtc' (see line 390)
drivers/gpu/drm/stm/ltdc.c
389 {
390 struct ltdc_device *ldev = crtc_to_ltdc(crtc);
^^^^
Dereferenced inside the function call
391 struct drm_color_lut *lut;
392 u32 val;
393 int i;
394
395 if (!crtc || !crtc->state)
^^^^
Too late.
396 return;
397
regards,
dan carpenter
