I just want the build errors fixed. I'm not asking for any particular fix. > I find it valid that a 'bool' can 'select' a 'tristate', to force it to 'y'. But a bool selecting a tristate that already =m does not force it to y AFAICT. I guess that would be an acceptable change/fix. Maybe. > Do you mean there is an issue with Kconfig, the parser?

That should be one way to fix the problem, yes. > -> change the symbol to a tristate? I thought about that, but I don't think that it will work. There is no separate module that is built for AC97 codec support. thanks, -- ~Randy -- To unsubscribe from this list: send the line "unsubscribe linux-kbuild" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
