But NEVER touch that kobject, it is not for your use at all.

Nope, you need your own struct device, do not use the kobject in the
cdev, again, it is NOT for use at all. It is private to a cdev and
I need to figure out a way to make it so that you can't even see it one
day to keep people from trying to use it.
good luck,
