[PATCH net-next] s390/qeth: use sysfs_emit() to instead of scnprintf()
From: ye.xingchen
Date: Sun Dec 04 2022 - 22:53:17 EST
From: ye xingchen <ye.xingchen@xxxxxxxxxx>
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.
