m501fb: don't return zero on failure path in sm501fb_probe() If no framebuffers found, sm501fb_probe() breaks off initialization, deallocates sm501fb_info, but returns zero. As a result, use after free can happen in sm501fb_remove(). The patch adds -ENODEV as a return value in this case. Found by Linux Driver Verification project (linuxtesting.org).
