gpio-led

    // state->irq = qemu_allocate_irq(gpio_led_irq_handler, obj, 0);
    qdev_init_gpio_in(DEVICE(obj), gpio_led_irq_handler, 1);


mchine creation

    // qemu_irq irq = GPIO_LED_STATE(led)->irq;
    qemu_irq irq = qdev_get_gpio_in(led, 0);
    qdev_connect_gpio_out(
                DEVICE(object_resolve_path("/machine/stm32/gpio[c]", NULL)), 12,
                irq);

the functional solution is commented out.
