Please don't do that. Even though it works for the current
implementation, comparing those pointers from a driver violates how
clkdev is supposed to work. The pointer returned by clk_get should only
be dereferenced by a driver to check if it is an error code. Anything
besides an error code is no business of the driver.

I looked through the patch briefly and did not see why we would need to
do this. Any hint?

Thanks,
Mike
