devm_gpiochip_add_data() makes the GPIO chip visible to consumers immediately. Since the chip sets .to_irq = mxc_gpio_to_irq, which calls irq_find_mapping(port->domain, offset), any to_irq() call between gpiochip registration and IRQ domain creation will operate on a NULL domain. Fix by moving devm_gpiochip_add_data() after the IRQ domain and generic irq chip are fully initialized, ensuring port->domain and the irq chip handlers are ready before the chip becomes visible to consumers.
