## Description

In the Linux kernel, the following vulnerability has been resolved:  drm/amd/display: Fix a NULL pointer dereference in amdgpu_dm_connector_add_common_modes()  In amdgpu_dm_connector_add_common_modes(), amdgpu_dm_create_common_mode() is assigned to mode and is passed to drm_mode_probed_add() directly after that. drm_mode_probed_add() passes &mode->head to list_add_tail(), and there is a dereference of it in list_add_tail() without recoveries, which could lead to NULL pointer dereference on failure of amdgpu_dm_create_common_mode().  Fix this by adding a NULL check of mode.  This bug was found by a static analyzer.  Builds with 'make allyesconfig' show no new warnings, and our static analyzer no longer warns about this code.
