If an OF node doesn't specify an interrupt property, 'uioinfo->irq' will be assigned to the UIO_IRQ_NONE value meaning no interrupt support. Trying to re-setup the irq later results in an error again and probing fails. To prevent this do not try to re-setup the irq if it was configured to UIO_IRQ_NONE by OF related code.
