From de9b58400a3ce6b9b6cc45f66c3f5e3d754becf1 Mon Sep 17 00:00:00 2001 From: Michael Straube Date: Thu, 12 Jul 2018 18:16:13 +0200 Subject: [PATCH] staging: rtl8188eu: use strlcpy instead of strncpy 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.
