Ma Ke f91b6e7844 drm/gma500: fix null pointer dereference in psb_intel_lvds_get_modes ... commit 2df7aac81070987b0f052985856aa325a38debf6 upstream. In psb_intel_lvds_get_modes(), the return value of drm_mode_duplicate() is assigned to mode, which will lead to a possible NULL pointer dereference on failure of drm_mode_duplicate(). Add a check to avoid npd.
