applied, thanks Paul!

I'm wondering, why did my cross-build of the SH defconfig in the 
timer tree not catch this? All i get (and got) are these warnings:

/home/mingo/tip/arch/sh/kernel/cpu/clock-cpg.c: In function 'cpg_clk_init':
/home/mingo/tip/arch/sh/kernel/cpu/clock-cpg.c:242: warning: 'arch_init_clk_ops' is deprecated (declared at /home/mingo/tip/arch/sh/include/asm/clock.h:58)
/home/mingo/tip/arch/sh/kernel/cpu/clock-cpg.c: In function 'arch_clk_init':
/home/mingo/tip/arch/sh/kernel/cpu/clock-cpg.c:256: warning: 'cpg_clk_init' is deprecated (declared at /home/mingo/tip/arch/sh/kernel/cpu/clock-cpg.c:237)

and time.o built without errors or warnings:

  CC      arch/sh/kernel/time.o
