In the case that the interrupts fail to result because of the interrupt-controller not yet being registered the platform_get_irq_byname() call will fail with -EPROBE_DEFER, but passing this into devm_request_threaded_irq() will result in -EINVAL being returned, the driver is therefor not reprobed later.
