Subject: [PATCH] scsi: message: fusion: Use sysfs_emit in show function
callsbacks
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.
