From: Chun-Hung Wu <chun-hung.wu@mediatek.com> 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 Signed-off-by: Chun-Hung Wu <chun-hung.wu@mediatek.com> --- kernel/time/sched_clock.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
