What puzzles me is that we only find these "#ifdef CONFIG_NETDEVICES" guards in this file and not in isdn_net.c, were all the ioctl commands guarded that way seem to be calling into. On first glance that doesn't make much sense. (Actually the idea of having ISDN without NETDEVICES is a bit puzzling too. But there are too many parts of the isdn subsystem that I'm unfamiliar with to say whether that can make sense.)
