It might have worked as built in code, I would be astounded if it ever
worked as a module on a standard kernel after that code was added.
name_to_kdev_t has been defined as this since at least 2.4.0-test1.

kdev_t __init name_to_kdev_t(char *line)

You cannot export a symbol marked __init and expect it to work.
