From cbb654052600c376d5ee3401c98a25d09d11a154 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marc-Andr=C3=A9=20Lureau?= Date: Fri, 25 Aug 2017 12:59:11 +0200 Subject: qlit: Tighten QLit list vs QList comparison MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We check that all members of the QLit list are also in the QList. We neglect to check the other direction. Fix that. While there, use QLIST_FOREACH_ENTRY() to simplify the code and break the loop on the first mismatch.
