Yes, I agree that needs dropped and something I missed when I cleaned
things up by hand. I verified that this is the only case in this series,
and all of the other series that I referenced on the cover letter, where
this occurred.

My Coccinelle semantic patch has a case when the parent rate is
dereferenced, and I'm not sure why that wasn't converted here since it
works elsewhere.

    long round_rate_name(struct clk_hw *hw_param, unsigned long rate_param,
                  unsigned long *parent_rate_param)
    {
    <...
    (
    - *parent_rate_param
    + req->best_parent_rate
    |
    - parent_rate_param
    + &req->best_parent_rate
    )
    ...>
    }

I'll wait a few weeks to send out a v2 to hopefully let big chunks of
this series get merged so that I don't have to send out 114 patches
again for a v2.
