From e8dcb8ae5121965ac8c89e6b277ac127e9d08452 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Tue, 15 May 2018 19:58:14 +0100 Subject: [PATCH] sdl: Move use of surface pointer below check for whether it is NULL MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In commit 2ab858c6c38ee1 we added a use of the 'surf' variable in sdl2_2d_update() that was unfortunately placed above the early-exit-if-NULL check. Move it to where it ought to be.
