[PATCH]: rtc: ds1685: Fix conditional in ds1685_rtc_sysfs_time_regs_{show,store}

[Joshua Kinard <kumba@gentoo.org>]

From: Joshua Kinard <kumba@gentoo.org>

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.

Fixes: aaaf5fbf56f1: "rtc: add driver for DS1685 family of real time clocks"
