From 2210ad006cb2c4851ce768f99c8a4816214fea0c Mon Sep 17 00:00:00 2001 From: Pekka Paalanen Date: Thu, 30 Mar 2017 15:48:06 +0300 Subject: [PATCH] libweston: move globals to weston_compositor_add_output() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Move the wl_output global management into weston_compositor_add_output() and weston_compositor_remove_output(). If weston_output_enable() fails, there is no need to clean up the global and the clients will not see a wl_output come and go.
