From b00eeaedece2e8cb1607cb015f10e572e2607c49 Mon Sep 17 00:00:00 2001 From: Joshua Kinard Date: Fri, 27 Feb 2015 15:51:59 -0800 Subject: [PATCH] drivers/rtc/rtc-ds1685.c: fix conditional in ds1685_rtc_sysfs_time_regs_{show,store} Fix a conditional statement checking for NULL in both ds1685_rtc_sysfs_time_regs_show and ds1685_rtc_sysfs_time_regs_store that was using a logical AND when it should be using a logical OR so that we fail out of the function properly if the condition ever evaluates to true.
