[PATCH 02/12] rtc: pcf2127: use sysfs_emit() instead of sprintf()

[alexandre . belloni]

From: Alexandre Belloni <alexandre.belloni@xxxxxxxxxxx>

Use sysfs_emit() instead of sprintf() in the sysfs show callback
(timestamp_show) to conform to the recommended sysfs attribute
formatting guidelines in Documentation/filesystems/sysfs.rst.
