Ah, thanks for tracking this down. I actually noticed the same
problem on an ARM build but did not realize it was from one of
the patches I had jut put in there myself.

I'm really glad I didn't send this to Linus cc:stable yet then.
Nicolas, in my randconfig branch, I've fixed this by adding

depends on HAVE_CLK

which I think is the right solution. I'll replace your patch
with one that does this if you don't mind.

I'd also remove the stable tag for this patch, because it can
have unintended side-effects on other architectures.

Arnd
