Subject: [PATCH] staging: rtl8188eu: use strlcpy instead of strncpy
Date: Thu, 12 Jul 2018 18:16:13 +0200 [thread overview]
Message-ID: <20180712161613.9317-1-straube.linux@gmail.com> (raw)
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.
