The ofnode_to_fdt() function may return a NULL pointer in multiple cases. Or, this function's return value is often passed directly to functions such as fdt_getprop() which end up dereferencing it, thus causing a NULL pointer exception. Don't allow ofnode_to_fdt() to return NULL, to avoid a NULL pointer dereference.
