Look > at the device code for what's needed for this.> Don't quite follow what you are saying. If you are saying that it needs to call class_get(parent) I don't think it's necessary as kobject code will grab the reference (to class's subsystem kset). All in all it seems to be working: [dtor@core ~]$ ls /sys/class/input_dev/ input0 input3 input4 input_dev_subclass [dtor@core ~]$ -- Dmitry - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||
