From e6e4d33f380fbfd85b909d16c9b639299e5c37a6 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Thu, 18 Aug 2022 22:59:51 +0200 Subject: [PATCH] um: 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.
