[PATCH v2 3/9] pktcdvd: use sysfs_emit() to instead of scnprintf()

From: Andy Shevchenko
Date: Fri Mar 10 2023 - 11:50:56 EST


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.
