You should instead make it:
return PTR_ERR(clk);
But you will need this patch for that to work:
http://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/drivers/clk/clk.c?id=a34cd4666f3da84228a82f70c94b8d9b692034ea
With this patch there is no need to overwrite any returned error
value with EPROBE_DEFER.
