From 3948a866822e77571dadaddebb6c5770ee1b1ad1 Mon Sep 17 00:00:00 2001 From: Alexandre Belloni Date: Mon, 11 Jan 2021 00:17:46 +0100 Subject: rtc: m41t80: constify m41t80_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.
