Since hardware may not MUST to use IRQ pin of max98090 as jack detect, the
driver can work well without it, can report jack trigger to CPU by a GPIO.

But here driver will register fail caused by failed to request irq.

I would say it's better to call request_threaded_irq() conditionally when max98090->irq is valid in the same max98090_probe(). Also code should return instantly in case of request_threaded_irq() fails for valid irq.

Now code is still printing needless error message in case max98090->irq is invalid or not specified and continue probing in case request_threaded_irq() fails for valid irq.
