Yes I know, but I wanted to ensure for runtime-pm we only return 0 on
success. Yes clk_enable should only return 0 on success and a negative
error code otherwise, but I prefer this. So will leave as-is.

It will be returned by the function. This is no different to how it
works today if you look at the code. I did think about checking it right
after this call and returning but then I am changing the behaviour and
that should be another patch. I am not sure why it is like this in the
first place, but I did not wish to introduce any different behaviour here.
