From 40364d2ee670a5a74318ef96c643762293ca95f0 Mon Sep 17 00:00:00 2001
From: Vlad Zahorodnii <vlad.zahorodnii@kde.org>
Date: Fri, 8 Apr 2022 12:44:33 +0300
Subject: [PATCH] Simplify code that announces available modes and current mode
If no mode has the current flag set, the first mode object will be
announced twice.
There's also no benefit from sending the current mode as last. If the
current mode changes, the compositor will send the current_mode event,
not the mode event.
BUG: 452318
(cherry picked from commit b40c4e3f4108b9a0be9b4f5d437e72f7c2aa3fea)
