I don't have to explicitly remove the files, do I? They go away
naturally when the device is unregistered?

I'm not so sure about this.  I can't see anything in the
drivers/base/core.c code that automatically deletes anything
other than device groups and attributes.

Hm, I really do think the attributes go away automatically when the
parent device does.

If not, gianfar_sysfs.c and niu.c want fixing too -- and we should
probably have a WARN_ON() in the sysfs code when it happens, if
possible.

I'll experiment (since I'm getting lost when I try to work it out by
inspection).
