Subject: [PATCH 1/3] clocksource/drivers/timer-milbeaut: Fix to enable one-shot timer
Date:   Mon, 25 Mar 2019 12:05:47 +0900
Message-Id: <1553483149-8922-2-git-send-email-sugaya.taichi@socionext.com>
In-Reply-To: <1553483149-8922-1-git-send-email-sugaya.taichi@socionext.com>
References: <1553483149-8922-1-git-send-email-sugaya.taichi@socionext.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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.
