From 8bc57e7f11971665b4a7886305dffcd27213d718 Mon Sep 17 00:00:00 2001 From: Bhumika Goyal Date: Thu, 5 Jan 2017 22:25:05 +0530 Subject: rtc: constify rtc_class_ops structures Declare rtc_class_ops structures as const as they are only passed as an argument to the function devm_rtc_device_register. This argument is of type const struct rtc_class_ops *, so rtc_class_ops structures having this property can be declared const.
