linux-next: build failure after merge of the clk tree

[Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>]

Hi Mike,

After merging the clk tree, today's linux-next build (x86_64
allmodconfig) failed like this:

In file included from include/trace/define_trace.h:90:0,
                 from include/trace/events/clk.h:198,
                 from drivers/clk/clk.c:26:

and many more ...

Caused by commit 0742a46667e3 ("clk: Add tracepoints for hardware
operations").

I have used the version of the clk tree from next-20150225 for today
(since yesterday's tree had a different build problem).
