From 6129369a96183f28c7912dfd37cb5869433aa904 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Noralf=20Tr=C3=B8nnes?= Date: Sat, 8 Sep 2018 15:46:29 +0200 Subject: [PATCH] drm/fb-helper: Improve error reporting in setup MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Improve error reporting in drm_fb_helper_fbdev_setup() by printing the error code. This is useful for drivers that choose to not fall over just because fbdev doesen't work, but still wants clues to why it failed. This way they don't have to provide an error message themselves.
