This doesn't make any sense. What are you trying to do here?
The get/put operations go together as one logical set - that's why you
get both if you're using clkdev, and why you're asked to implement both
__clk_get() and __clk_put() in arch code to do whatever's necessary
with the clock.
Let me guess, and say that clk_put() is not a release method. It's a
method for drivers to say "I'm done with this clock" and for the arch
code to reverse the effects of __clk_get()/clk_get().
Currently, its only user is to balance module counts.
