How does this "fix the memory" ?  Is the memory faulty?

This makes no sense.  clk_get() itself doesn't allocate any memory.  As
usual, you act as a mechanical automatom which doesn't understand what
you're doing or you just guess.  I don't care which it is, you are a
danger to the kernel by doing this.  As many other experienced kernel
developers have told you, please stop.

In any case, I'm NAKing your patch as there's better ways to solve this.
That's where experience and research come in.

Nevertheless, thanks for pointing out the oversight, and I notice that
there are a few more cases too.
