Subject: [PATCH V2] rtc: rtc-pcf2123: replace strict_strtoul() with kstrtoul()

The usage of strict_strtoul() is not preferred, because
strict_strtoul() is obsolete. Thus, kstrtoul() should be
used.

Signed-off-by: Jingoo Han <jg1.han@...sung.com>

Changes since v1:
- Used return code from kstrtoul().
