From 7574cc5837f301fa55c1a21a4df2a713f67de6c2 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Thu, 18 Aug 2022 23:02:20 +0200 Subject: [PATCH] ipv6: move from strlcpy with unused retval to strscpy Follow the advice of the below link and prefer 'strscpy' in this subsystem. Conversion is 1:1 because the return value is not used. Generated by a coccinelle script.
