Subject: [PATCH 08/14] rtc: m41t80: use rtc_lock/rtc_unlock
Date: Tue, 19 Jan 2021 23:06:46 +0100 [thread overview]
Message-ID: <20210119220653.677750-8-alexandre.belloni@bootlin.com> (raw)
In-Reply-To: <20210119220653.677750-1-alexandre.belloni@bootlin.com>
Avoid accessing directly rtc->ops_lock and use the RTC core helpers.
