Subject: [PATCH 07/17] rtc: pcf2127: remove pcf2127_rtc_alrm_ops
Date:   Mon, 11 Jan 2021 00:17:42 +0100
Message-Id: <20210110231752.1418816-8-alexandre.belloni@bootlin.com>

Move the alarm callbacks in pcf2127_rtc_ops and use RTC_FEATURE_ALARM to
signal to the core whether alarms are available instead of having a
supplementary struct rtc_class_ops without alarm callbacks.
