As the tda998x also makes use of the interrupt, it would be trivial to avoid instantiating the tda9950 device if there's no interrupt. tda9950 does require it, and if it's missing, then it isn't functional. No point wasting memory on the struct device. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last!
