From 9a742e52b1784553b3932eae8970bf96c26e8402 Mon Sep 17 00:00:00 2001 From: "Huang, Tao" Date: Thu, 12 Mar 2015 15:48:12 +0800 Subject: [PATCH] rtc: HYM8563: don't call rtc_year_days If i2c error, the driver may call rtc_year_days with month -1, which will cause crash. Fix this by never call rtc_year_days at all.
