The error handling doesn't work here because "nuc900_audio->irq_num" is unsigned. Also we should be checking for < 0 and not <= 0 but I believe that's harmless. The platform_get_irq() comments don't talk about the return values...
Sorry for this patch. I will fix it and send you updated patch. Thanks for point it.
