  "description": "In the Linux kernel, the following vulnerability has been resolved:  drm/amd/display: Add \u0027replay\u0027 NULL check in \u0027edp_set_replay_allow_active()\u0027  In the first if statement, we\u0027re checking if \u0027replay\u0027 is NULL. But in the second if statement, we\u0027re not checking if \u0027replay\u0027 is NULL again before calling replay-\u003Efuncs-\u003Ereplay_set_power_opt().  if (replay == NULL \u0026\u0026 force_static)     return false;  ...  if (link-\u003Ereplay_settings.replay_feature_enabled \u0026\u0026     replay-\u003Efuncs-\u003Ereplay_set_power_opt) { \treplay-\u003Efuncs-\u003Ereplay_set_power_opt(replay, *power_opts, panel_inst); \tlink-\u003Ereplay_settings.replay_power_opt_active = *power_opts; }  If \u0027replay\u0027 is NULL, this will cause a null pointer dereference.  Fixes the below found by smatch: drivers/gpu/drm/amd/amdgpu/../display/dc/link/protocols/link_edp_panel_control.c:895 edp_set_replay_allow_active() error: we previously assumed \u0027replay\u0027 could be null (see line 887)",
