[PATCH linux-next] leds: leds-lm3533: Convert to use sysfs_emit() APIs

[zhangsongyi.cgel]

From: zhang songyi <zhang.songyi@zte.com.cn>

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.
