Subject: pktcdvd: use sysfs_emit() to instead of scnprintf()
Git-commit: 3bb5746c26cdfcc354af4867c02f1e0ec1131a62
Patch-mainline: v6.5-rc1
References: bsc#1216436
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.
