From 4ec2364f4910234030906b3f824b51c0d7065334 Mon Sep 17 00:00:00 2001 From: Xunlei Pang Date: Thu, 22 Jan 2015 02:31:52 +0000 Subject: rtc: Update rtc-dev to use y2038-safe time interfaces Currently, rtc-dev.c uses y2038 problematic rtc_tm_to_time() and rtc_time_to_tm(). So replace them with their corresponding y2038-safe versions: rtc_tm_to_time64() and rtc_time64_to_tm().
