Hello Leo Chen,
This is a semi-automatic email about new static checker warnings.
The patch 7ef414375fcc: "drm/amd/display: Various logs added" from
Aug 29, 2022, leads to the following Smatch complaint:
./drivers/gpu/drm/amd/display/dc/bios/bios_parser2.c:1862
get_firmware_info_v3_2()
warn: variable dereferenced before check 'smu_info_v3_2' (see line 1861)
./drivers/gpu/drm/amd/display/dc/bios/bios_parser2.c
1860
DATA_TABLES(smu_info));
1861 DC_LOG_BIOS("gpuclk_ss_percentage (unit of 0.001
percent): %d\n", smu_info_v3_2->gpuclk_ss_percentage);
^^^^^^^^^^^^^^^
Log adds a crash.
1862 if (!smu_info_v3_2)
^^^^^^^^^^^^^
Too late.
1863 return BP_RESULT_BADBIOSTABLE;
1864
regards,
dan carpenter
