Subject: [PATCH net-next] sfc: Convert to use sysfs_emit_at() API
Date: Thu, 8 Dec 2022 15:23:27 +0800 (CST) [thread overview]
Message-ID: <202212081523277319144@zte.com.cn> (raw)
From: ye xingchen <ye.xingchen@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.
