Subject: scsi: csiostor: Convert sysfs snprintf() to sysfs_emit()
Git-commit: 9acb9f0efb930de37f65718e35e09ddd20c80961
Patch-mainline: v6.1-rc1
References: jsc#PED-1504

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.
