Wrapper functions that just call another function?  Why?

As per the documentation in the kernel source tree[1], I am now allowed
to mock you mercilessly for thinking that you know more than the kernel,
and are just providing an "empty" function just to shut it up from
complaining about no release function at all.  Did you stop to think
about _why_ the kernel was warning you about this, and how would an
empty function solve anything?

Sorry, I can never accept code that does this in the kernel, even in
staging, which says a lot...

thanks,
