Subject: [PATCH linux-next v4 1/4] time/sched_clock: Export sched_clock_register()

From: Chun-Hung Wu <[email protected]>

clocksource driver may use sched_clock_register()
to resigter itself as a sched_clock source.
Export it to support building such driver
as module, like timer-mediatek.c

You're the sender, so you shall sign off all of the patches. Please do.

I can't give you a Reviewed-by tag because of that.
