Subject: [PATCH] scsi: fnic: Use sysfs_emit in show function callsbacks
Message-ID: <Y6gPPLI3nfKoDVVe@qemulion>
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
Precedence: bulk

According to Documentation/filesystems/sysfs.rst, the show() callback
function of kobject attributes should strictly use sysfs_emit() instead
of sprintf() family functions. So, make this change.
Issue identified using the coccinelle device_attr_show.cocci script.
