From d0e3d95fa3442c6ff32f7fed3e0d2eeb2248ef9f Mon Sep 17 00:00:00 2001 From: Phil Sutter Date: Fri, 20 Oct 2017 13:24:36 +0200 Subject: libxt_recent: Remove ineffective checks for info->name In struct xt_recent_mtinfo{,_v1}, field 'name' is an array, not a pointer. So there is no point in comparing it against NULL. Changing the check to make sure it's content is not an empty string is pointless either, since a non-empty default string is used and the argument parser will refuse empty strings as --name argument. So simply get rid of the checks altogether.
