This function still expects to get a (struct clk *) here, but...

...here a (struct clk_core *) is stored.

Making this a static inline will benefit you with type checking at
compilation time.

Hmm, I'm not following. clk_to_clk_core() returns clk->core, while
clk_core_to_clk() simply casts whatever the former returns into a
pointer to struct clk?
Also this should be a static inline to benefit from compiler type checking.
