Subject: [PATCH v1 3/4] leds: trigger: gpio: Use sysfs_emit() to instead of s*printf()
Date:   Fri,  3 Nov 2023 21:53:09 +0200

Follow the advice of the Documentation/filesystems/sysfs.rst and show()
should only use sysfs_emit() or sysfs_emit_at() when formatting the
value to be returned to user space.
