I don't know. Hopefully, Greg has a good idea. But it sounds like a
general problem that a lot of cdev's actually suffer from without
realizing. Perhaps we need a more general solution. Some way for the
cdev to reference its containing structure in a way that it's designed
for such that anyone writing a driver will do the right thing without
needing to dive into the kobjects.
