From c0decac19da3906d9b66291e57b7759489e1170f Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Mon, 10 Sep 2018 08:19:14 -0400 Subject: media: use strscpy() instead of strlcpy() The implementation of strscpy() is more robust and safer. That's now the recommended way to copy NUL terminated strings.

It does require gcc 4.6, because of this bug in earlier versions: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=10676 Since commit cafa0010cd51 ("Raise the minimum required gcc version to 4.6"), this is the case.
