From 8a33d96bd178d5f49cc5c1898e4cda08e221d2db Mon Sep 17 00:00:00 2001 From: XueBing Chen Date: Wed, 25 May 2022 16:51:01 +0800 Subject: x86/setup: Use strscpy() to replace deprecated strlcpy() strlcpy() is marked deprecated and should not be used, because it doesn't limit the source length. The preferred interface for when strlcpy()'s return value is not checked (truncation) is strscpy().
