Thanks John for the tip. I will try to be better at that in the followup.

For this specific patch, I am adding this new API because the Samsung
PLL driver (drivers/clk/samsung/clk-pll.c) currently is using the
variable 'timekeeping_suspended' to detect timeouts before the
clocksource is initialized or timekeeping itself is suspended. My
patch series aims to modularize the Samsung PLL driver. So to keep the
driver's functionality intact, I need to add this additional API.
