Well, if you're the driver in on, then the fact that kobj_open_file() isn't stable doesn't matter. If you're in ON, when they change it they need to change all consumers of that interface. Apart from kobj_open_file(), we've also used specific daemon which will download the file through a ioctl; that is what we do for the SPARC graphics hardware.
