Subject: [PATCH 08/17] rtc: pcf85063: remove pcf85063_rtc_ops_alarm
Date:   Mon, 11 Jan 2021 00:17:43 +0100

Move the alarm callbacks in pcf85063_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.
