This isn't true for clk_enable().

It's frustrating that you make the same mistake over and over and you
are fine with doing that.  If you make a mistake and you are fixing a
bug, then hopefully you fix more bugs than you introduce.  If you make a
mistake and you are doing a cleanup then you are really just introducing
bugs and that's not helpful.  I wish you would find something useful to
do instead of sending these patches.  :(
