Subject: [PATCH] iio: trigger: stm32-timer: Convert to use sysfs_emit_at() API
Date: Wed, 7 Dec 2022 15:55:22 +0800 (CST) [thread overview]
Message-ID: <202212071555220843038@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.
