Hi all, The function of_overlay_fix_path returns NULL in certain error cases but of_overlay_apply_symbols (which is the only caller) does not check the return value. For broken overlays this may result in a null pointer exception. Fix this by checking the return value and inform the user what exactly went wrong. To this end, improve the error handling in of_overlay_apply_tree. The thread [0] gives a bit more context.
