I would leave out the comment above, it's a leftover from
the clk_add_alias() version that we don't need because of
of_clk_get().

How about drop the comment on clocks being removed above.
It no longer an issue, so maybe something like this instead:
* Note that we look up the clock lazily when the consumer
* driver does of_clk_get() and initialize a NULL clock here.

Then the above comment can be removed too.
