Subject: [PATCH] staging: rtl8188eu: use strlcpy instead of strncpy
Git-commit: de9b58400a3ce6b9b6cc45f66c3f5e3d754becf1
Patch-mainline: v4.19-rc1
References: FATE#326906
Use strlcpy instead of strncpy to avoid gcc 8 warning:
Warning: '__builtin_strncpy' specified bound 16 equals destination size [-Wstringop-truncation]
The maximum length of the source string including terminating null is 5.
Hence it always fits in the destination buffer of length 16.
