Just checking this didn't fall through the cracks, as its absence
causes several arch breakage on linux-next for several days now:

(.init.text+0xf968): undefined reference to `clk_add_alias'

x86:     http://kisskb.ellerman.id.au/kisskb/buildresult/12448913/
powerpc: http://kisskb.ellerman.id.au/kisskb/buildresult/12449785/
parisc:  http://kisskb.ellerman.id.au/kisskb/buildresult/12449940/

and possibly others I've missed.

Paul.
