In the other email you say you have to change. Here you say, you don't
have to change. Hopefully, you didn't have to change much -- I was aiming
for that. If there was agreement about removing these functions, I was
planning on helping move the current users after this patch merged.

I think in the long run this will result in less changes for you and more
readable code. If clk_register() adds another optional param, you can't
get around that without having to write more wrapper functions or changing
any existing ones you might have. But with this struct, the common clock
code can be written in a way so that the a value of 0 for the new param
defaults to the behavior that was there before the param was added.

Something to think about: With these wrapper calls, one would do a lot of
kalloc and copying of small items when one knows at compile time what the
clocks are going to be.

Anyway, I understand that some people see value in this. That's why I'm
bringing it up for discussion instead of just doing it in my patch.
