From 7bbdf0f8922ab0fc6f805851f6bb1a9d271414f4 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Tue, 26 May 2020 08:22:47 +0200 Subject: [PATCH] hw/display/xlnx_dp: Replace disabled DPRINTF() by error_report() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit DPRINTF() calls are disabled by default, so when unexpected data is used, the whole process abort without information. Display a bit of information with error_report() before crashing. Signed-off-by: Philippe Mathieu-Daudé Reviewed-by: Edgar E.
