From a038c3aa9f3afe9ab97a75827789859fb4af5767 Mon Sep 17 00:00:00 2001 From: Bibek Basu Date: Fri, 14 Aug 2015 20:44:02 +0200 Subject: [PATCH] rtc: as3722: correct month value The RTC month value is 1-indexed, but the kernel assumes it is 0-indexed. This may result in the RTC not rolling over correctly.
