From 3339aa186cc11fece96b77e2d4bc80678f90b440 Mon Sep 17 00:00:00 2001 From: Javier Martinez Canillas Date: Tue, 11 Oct 2022 18:51:34 +0200 Subject: [PATCH] drm/simpledrm: Do not call drm_atomic_add_affected_planes() There's no need to add planes to the atomic state. Remove the call to drm_atomic_add_affected_planes() from simpledrm. On full modesets, the DRM helpers already add a CRTC's planes to the atomic state; see drm_atomic_helper_check_modeset(). There's no reason to call drm_atomic_add_affected_planes() unconditionally in the CRTC's atomic_check() in simpledrm. It's also too late, as the atomic_check() of the added planes will not be called before the commit.
