Up until commit6a45b0e258("gpiolib: Introduce gpiochip_irqchip_add_domain()") all irq_domains were allocated by gpiolib itself and thus gpiolib also takes care of freeing it. With gpiochip_irqchip_add_domain() a user of gpiolib can associate an irq_domain with the gpio_chip. This irq_domain is not managed by gpiolib and therefore must not be freed by gpiolib.
