Upstream-Status: Backport [https://github.com/qemu/qemu/commit/61c34fc] Signed-off-by: Kai Kang From 61c34fc194b776ecadc39fb26b061331107e5599 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Mon, 28 Nov 2022 21:27:37 +0100 Subject: [PATCH] hw/display/qxl: Have qxl_log_command Return early if no log_cmd handler MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Only 3 command types are logged: no need to call qxl_phys2virt() for the other types. Using different cases will help to pass different structure sizes to qxl_phys2virt() in a pair of commits.
