From 9476b67bf9fa4be0d16a36d1d14685b114cffdb9 Mon Sep 17 00:00:00 2001 From: Alexandre Belloni Date: Mon, 11 Jan 2021 00:17:49 +0100 Subject: [PATCH] rtc: rv3029: constify rv3029_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.
