Ma Ke cdd617c690 drm/gma500: fix null pointer dereference in cdv_intel_lvds_get_modes 
commit cb520c3f366c77e8d69e4e2e2781a8ce48d98e79 upstream.

In cdv_intel_lvds_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.
