[PATCH v1 3/4] leds: trigger: gpio: Use sysfs_emit() to instead of s*printf()

From: Andy Shevchenko
Date: Fri Nov 03 2023 - 16:56:00 EST


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.
