Subject: [PATCH v1 3/9] pktcdvd: use sysfs_emit() to instead of scnprintf()
Date: Fri, 20 Jan 2023 00:08:03 +0200 [thread overview]
Message-ID: <20230119220809.5518-3-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20230119220809.5518-1-andriy.shevchenko@linux.intel.com>
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.
