You don't need to check CONFIG_ACPI as acpi_gpiochip_request_interrupts()
will be stubbed out if !CONFIG_ACPI.
Should you call acpi_gpiochip_free_interrupts() somewhere to unregister
the interrupts as well?
Even better if you can switch your driver to use GPIOLIB_IRQCHIP all
this is done automatically for you.
