Sorry, but creating an empty release function just to shut the kernel up
is NOT how to properly do this, you all know better.  This is totally
broken.  The kernel was telling you what you had to do, don't think that
you are being smarter than it by doing this, otherwise we would have
never had the kernel spit out that error in the first place, right?

Now I will ask you to follow the proper Intel kernel review rules and
get proper approval for the patchset before submitting it to us again,
as basic things like this are not supposed to be caught by us, but by
your internal review process first.

good luck!
