From: kernel test robot <[email protected]> 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().
