Si ctx->steps es cero, se omite el procesamiento del bucle de pasos ECC y la variable ret permanece sin inicializar. Posteriormente, se verifica y se devuelve, lo que genera un comportamiento indefinido y puede causar resultados impredecibles en el espacio de usuario o fallos del kernel. Este escenario puede activarse en casos extremos, como una geometría mal configurada, un uso indebido del motor ECC o si ctx->steps no se valida tras la inicialización. Inicialice ret a cero antes del bucle para garantizar un comportamiento correcto y seguro, independientemente del valor de ctx->steps.
