I don't know why kbuild didn't catch these before, but it looks like we
really need to include device.h in cdev.h now to fix up these build
warnings, right?

I'll try that out and rebase the char-misc-testing tree in the morning
to see if that fixes the build problems...

Yeah, I think the kbuild robot missed the series because the vger
mailing lists were dropping this series :(

I also don't know why my kernel config didn't catch this warning but
I reproduced and fixed it with the kbuild's config. I'll send an updated
patch which adds a include device.h line to cdev.h momentarily.
