Currently, clocksource_register() and __clocksource_register_scale()
functions always return 0, it's pointless, make functions void.
And remove the dead code that check the clocksource_register_hz()
return value.
......

-static inline int clocksource_register_hz(struct clocksource *cs, u32 hz)

This doesn't make sense - you are still returning a value on a function
declared void, and the return is now from a function that doesn't return
anything either ?!?!
Doesn't this throw a compile-time warning??
It depends on the compiler.
Recent gcc allow it.
I don't know if it is actually valid C though.
There is no excuse for it on lines like the above though.
Can you please resend with that fixed against 3.14-rc1 ?
Thanks,
