Subject: [PATCH] scsi: mptfusion: use strlcpy() instead of strncpy()
Git-commit: 6f5c592ce936b2a2f5d05d3112b550bb039050f2
Patch-mainline: v4.16-rc1
References: bsc#1118139

drivers/message/fusion/mptbase.c: In function 'mpt_display_event_info':
./include/linux/string.h:245:9: warning: '__builtin_strncpy' specified
bound 100 equals destination size [-Wstringop-truncation]
We need to use strlcpy() to make sure the dest string is nul-terminated.
