Well, as you are not the only one misinterpreting the purpose, I
guess it is more about the clk_is_enabled() function itself. Uwe was
very right, that it will lead to patches using it in a wrong way.

Using the common enable/disable functions does no harm to our workaround
and we will use it.

Thanks for taking the time to raise those questions and surface those
critical interpretations early!
