Do not use NO_IRQ. Use <= 0 instead, or just test against zero for no IRQ. It would also be nice to offer this facility to non-DT platforms via client->irq. Not every arch in the Linux kernel uses DT.
At least for the DT part, I'd suggest to not ask for interrupt directly but use a proper gpios property. The can of course be converted to priv->int_irq in some tda998x_dt_probe.
