From c30f55a7b1336cdfeac74c7931ebff40a32e72b7 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Mon, 22 Jun 2015 13:37:46 +0300 Subject: [PATCH] drm/atomic: Don't set crtc_state->enable manually The enable field needs to be kept in sync with the mode_blob field. Call drm_atomic_set_mode_prop_for_crtc() instead of setting enable to false in order to dereference the mode blob correctly. v2: - Check the return value of drm_atomic_set_mode_prop_for_crtc() - Drop the num_connectors local variable Signed-off-by: Laurent Pinchart Signed-off-by: Daniel Vetter --- drivers/gpu/drm/drm_atomic_helper.c | 10 +++++++--- 1 file changed, 7 insertions(+), 3 deletions(-) diff --git a/drivers/gpu/drm/drm_atomic_helper.c b/drivers/gpu/drm/drm_atomic_helper.c index b06a607db6c2..5b59d5ad7d1c 100644 --- a/drivers/gpu/drm/drm_atomic_helper.c +++ b/drivers/gpu/drm/drm_atomic_helper.c @@ -1555,10 +1555,14 @@ static int update_output_state(struct drm_atomic_state *state, if (crtc == set->crtc) continue; - crtc_state->enable = - drm_atomic_connectors_for_crtc(state, crtc); - if (!crtc_state->enable) + if (!drm_atomic_connectors_for_crtc(state, crtc)) { + ret = drm_atomic_set_mode_prop_for_crtc(crtc_state, + NULL); + if (ret < 0) + return ret; + crtc_state->active = false; + } } return 0; -- 2.11.0
