It's a kref, no need to typecheck anything, if it isn't the right
structure it will usually just break the build anyway. So this isn't
really needed, especially as most of the to_* calls in the kernel are
macros like this.
I'll take it, but really, this isn't needed, you are only trying to
protect yourself from your own coding :)
