Subject: [PATCH 13/17] rtc: rv3028: constify rv3028_rtc_ops
Date: Mon, 11 Jan 2021 00:17:48 +0100 [thread overview]
Message-ID: <20210110231752.1418816-14-alexandre.belloni@bootlin.com> (raw)
In-Reply-To: <20210110231752.1418816-1-alexandre.belloni@bootlin.com>
Use RTC_FEATURE_ALARM to signal to the core whether alarms are available
instead of changing the global struct rtc_class_ops, allowing to make it
const.
