drivers/scsi/isci/init.c:140:8-16: WARNING: use scnprintf or sprintf


 From Documentation/filesystems/sysfs.txt:
  show() must not use snprintf() when formatting the value to be
  returned to user space. If you can guarantee that an overflow
  will never happen you can use sprintf() otherwise you must use
  scnprintf().
