From 19588d50a2d67c3ca40f4609f59cbda9e55bdfb5 Mon Sep 17 00:00:00 2001 From: Alexandre Belloni Date: Mon, 11 Jan 2021 00:17:50 +0100 Subject: [PATCH] rtc: rv3032: constify rv3032_rtc_ops 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.
