That's right if you have GpioInt -resource somewhere you need to
translate to Linux IRQ number (and use it via irqchip instead of gpiolib
API).

What was done for I2C core with addition of acpi_dev_gpio_irq_get() is
that now it automatically takes first GpioInt of an I2C device and
assigns the translated IRQ number to client->irq if it is not yet
assigned to a valid IRQ.
