sm501fb: don't return zero on failure path in sm501fb_start() If fbmem iomemory mapping failed, sm501fb_start() breaks off initialization, deallocates resources, but returns zero. As a result, double deallocation can happen in sm501fb_stop(). Found by Linux Driver Verification project (linuxtesting.org).
