Description
In the Linux kernel, the following vulnerability has been resolved:
drm/panel: fix a possible null pointer dereference
In versatile_panel_get_modes(), the return value of drm_mode_duplicate()
is assigned to mode, which will lead to a NULL pointer dereference
on failure of drm_mode_duplicate(). Add a check to avoid npd.
