[PATCH] iio: mma8452: Convert to use sysfs_emit_at() API

From: ye.xingchen
Date: Tue Dec 06 2022 - 21:04:55 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.
