From 5552aad35d439ad96ae55f0e3db25b6268170259 Mon Sep 17 00:00:00 2001 From: Fabien Dessenne Date: Tue, 6 Sep 2016 09:41:48 +0200 Subject: [PATCH] drm/sti: fix atomic_disable check When a drm_plane is being disabled, its ->crtc member is set to NULL before the .atomic_disable() func is called. To get the crtc of the plane, read old_state->crtc instead of drm_plane->crtc Signed-off-by: Fabien Dessenne Acked-by: Vincent Abriou --- drivers/gpu/drm/sti/sti_cursor.c | 6 +++--- drivers/gpu/drm/sti/sti_gdp.c | 6 +++--- drivers/gpu/drm/sti/sti_hqvdp.c | 6 +++--- 3 files changed, 9 insertions(+), 9 deletions(-) diff --git a/drivers/gpu/drm/sti/sti_cursor.c b/drivers/gpu/drm/sti/sti_cursor.c index 651f231c4615..cca75bddb9ad 100644 --- a/drivers/gpu/drm/sti/sti_cursor.c +++ b/drivers/gpu/drm/sti/sti_cursor.c @@ -309,15 +309,15 @@ static void sti_cursor_atomic_disable(struct drm_plane *drm_plane, { struct sti_plane *plane = to_sti_plane(drm_plane); - if (!drm_plane->crtc) { + if (!oldstate->crtc) { DRM_DEBUG_DRIVER("drm plane:%d not enabled\n", drm_plane->base.id); return; } DRM_DEBUG_DRIVER("CRTC:%d (%s) drm plane:%d (%s)\n", - drm_plane->crtc->base.id, - sti_mixer_to_str(to_sti_mixer(drm_plane->crtc)), + oldstate->crtc->base.id, + sti_mixer_to_str(to_sti_mixer(oldstate->crtc)), drm_plane->base.id, sti_plane_to_str(plane)); plane->status = STI_PLANE_DISABLING; diff --git a/drivers/gpu/drm/sti/sti_gdp.c b/drivers/gpu/drm/sti/sti_gdp.c index 1d5ebe4c51db..083c0aca57e2 100644 --- a/drivers/gpu/drm/sti/sti_gdp.c +++ b/drivers/gpu/drm/sti/sti_gdp.c @@ -846,15 +846,15 @@ static void sti_gdp_atomic_disable(struct drm_plane *drm_plane, { struct sti_plane *plane = to_sti_plane(drm_plane); - if (!drm_plane->crtc) { + if (!oldstate->crtc) { DRM_DEBUG_DRIVER("drm plane:%d not enabled\n", drm_plane->base.id); return; } DRM_DEBUG_DRIVER("CRTC:%d (%s) drm plane:%d (%s)\n", - drm_plane->crtc->base.id, - sti_mixer_to_str(to_sti_mixer(drm_plane->crtc)), + oldstate->crtc->base.id, + sti_mixer_to_str(to_sti_mixer(oldstate->crtc)), drm_plane->base.id, sti_plane_to_str(plane)); plane->status = STI_PLANE_DISABLING; diff --git a/drivers/gpu/drm/sti/sti_hqvdp.c b/drivers/gpu/drm/sti/sti_hqvdp.c index c6b25f4fad6a..d9ff79ebc366 100644 --- a/drivers/gpu/drm/sti/sti_hqvdp.c +++ b/drivers/gpu/drm/sti/sti_hqvdp.c @@ -1215,15 +1215,15 @@ static void sti_hqvdp_atomic_disable(struct drm_plane *drm_plane, { struct sti_plane *plane = to_sti_plane(drm_plane); - if (!drm_plane->crtc) { + if (!oldstate->crtc) { DRM_DEBUG_DRIVER("drm plane:%d not enabled\n", drm_plane->base.id); return; } DRM_DEBUG_DRIVER("CRTC:%d (%s) drm plane:%d (%s)\n", - drm_plane->crtc->base.id, - sti_mixer_to_str(to_sti_mixer(drm_plane->crtc)), + oldstate->crtc->base.id, + sti_mixer_to_str(to_sti_mixer(oldstate->crtc)), drm_plane->base.id, sti_plane_to_str(plane)); plane->status = STI_PLANE_DISABLING; -- 2.20.1
