That's good.

I'd like to enable it for only files under drivers/clk/ but it doesn't
seem to work. I'm not asking to enable it at the toplevel Makefile. I'm
asking to enable it for drivers/clk/ so nobody has to think about it now
that you've done the hard work of getting the numbers in this directory
down to zero or close to zero.
