As far as I can tell, struct clk is declared in include/linux/clk.h.
It is a forward declaration, meaning that you cannot access the fields
of this composite type. But why would you need to do that? In order to
read the rate of a clock, you should use clk_get_rate() which is
defined in the same header.
