3.16.51-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Jonas Gorski <jonas.gor...@gmail.com>
commit 585e0e9d02a690c29932b2fc0789835c7b91d448 upstream.
Make the behaviour of clk_get_rate consistent with common clk's
clk_get_rate by accepting NULL clocks as parameter. Some device
drivers rely on this, and will cause an OOPS otherwise.
