[PATCH 04/15] clocksource/drivers/timer-milbeaut: Fix to enable one-shot timer

From: Daniel Lezcano
Date: Thu May 09 2019 - 07:13:42 EST


From: Sugaya Taichi <sugaya.taichi@xxxxxxxxxxxxx>

Fix mlb_set_oneshot_state() to enable one-shot timer.
The function should stop and start a timer, but "start" statement was
dropped. Kick the register to start one-shot timer.

Fixes: b58f28f306db ("clocksource/drivers/timer-milbeaut: Introduce timer for Milbeaut SoCs")
