In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Fix variable deferencing before NULL check in edpsetupreplay()
In edpsetupreplay(), 'struct dc *dc' & 'struct dmub_replay *replay' was dereferenced before the pointer 'link' & 'replay' NULL check.
Fixes the below: drivers/gpu/drm/amd/amdgpu/../display/dc/link/protocols/linkedppanelcontrol.c:947 edpsetup_replay() warn: variable dereferenced before check 'link' (see line 933)
