From aaf7642e98917fc95c260cbee98d2f426754b265 Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Fri, 10 Jun 2016 12:50:39 +0300 Subject: [PATCH] drm/omap: fix plane check when crtc is disabled I sometimes see: [drm:drm_framebuffer_remove [drm]] *ERROR* failed to reset crtc ed2a6c00 when fb was deleted: -22 which comes from drm_framebuffer_remove() when it's disabling the crtc with zeroed drm_mode_set. The problem in omap_plane_atomic_check() is that it will use those zeroed fields to verify if the setup is correct. This patch makes omap_plane_atomic_check() return 0 if the crtc is disabled.
