[PATCH] media: siano: Convert to use sysfs_emit_at() API

From: ye.xingchen
Date: Wed Dec 07 2022 - 22:40:24 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.
