File U_present-wnmd-Relax-assertion-on-CRTC-on-abort_vblank.patch of Package xorg-x11-server.22973
From 0e60139064b84b856c59e5a456e26c60710b1b69 Mon Sep 17 00:00:00 2001 From: Olivier Fourdan <ofourdan@redhat.com> Date: Mon, 18 Nov 2019 17:28:45 +0100 Subject: [PATCH] present/wnmd: Relax assertion on CRTC on abort_vblank() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Currently, the function `present_wnmd_abort_vblank()` would fail if the given `crtc` is NULL. However, `xwl_present_get_crtc()` can return `NULL` under some circumstances, which would cause an unexpected termination of Xwayland in such a case, caused by the assertion failure being triggered. Remove the assertion, considering that the `crtc` isn't actually used in neither `present_wnmd_abort_vblank()` nor `xwl_present_abort_vblank()`.
