[PATCH] iio: health: afe440x: Convert to use sysfs_emit_at() API
From: ye.xingchen
Date: Wed Dec 07 2022 - 02:37:56 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.
