Stop looking at it. Daniel pointed out that the drm_framebuffer_put() in the plane cleanup indicates that the driver doesn't shut things down cleanly. To do that we should be able to just call drm_atomic_helper_shutdown(). Not really sure the current cleanup sequence is actually sane, but whatever. v2: Replace the drm_framebuffer_put() with drm_atomic_helper_shutdown() (Daniel) Cc: Daniel Vetter Cc: Boris Brezillon Signed-off-by: Ville Syrjälä Link: https://patchwork.freedesktop.org/patch/msgid/20180405151400.11326-10-ville.syrjala@linux.intel.com Reviewed-by: Daniel Vetter --- diff --git a/drivers/gpu/drm/atmel-hlcdc/atmel_hlcdc_dc.c b/drivers/gpu/drm/atmel-hlcdc/atmel_hlcdc_dc.c index c1ea5c36b006..843cac222e60 100644 --- a/drivers/gpu/drm/atmel-hlcdc/atmel_hlcdc_dc.c +++ b/drivers/gpu/drm/atmel-hlcdc/atmel_hlcdc_dc.c @@ -681,6 +681,7 @@ static void atmel_hlcdc_dc_unload(struct drm_device *dev) drm_fb_cma_fbdev_fini(dev); flush_workqueue(dc->wq); drm_kms_helper_poll_fini(dev); + drm_atomic_helper_shutdown(dev); drm_mode_config_cleanup(dev); pm_runtime_get_sync(dev->dev); diff --git a/drivers/gpu/drm/atmel-hlcdc/atmel_hlcdc_plane.c b/drivers/gpu/drm/atmel-hlcdc/atmel_hlcdc_plane.c index 15c74527ba49..1aecc74cc463 100644 --- a/drivers/gpu/drm/atmel-hlcdc/atmel_hlcdc_plane.c +++ b/drivers/gpu/drm/atmel-hlcdc/atmel_hlcdc_plane.c @@ -817,16 +817,6 @@ static void atmel_hlcdc_plane_atomic_disable(struct drm_plane *p, atmel_hlcdc_layer_read_reg(&plane->layer, ATMEL_HLCDC_LAYER_ISR); } -static void atmel_hlcdc_plane_destroy(struct drm_plane *p) -{ - struct atmel_hlcdc_plane *plane = drm_plane_to_atmel_hlcdc_plane(p); - - if (plane->base.fb) - drm_framebuffer_put(plane->base.fb); - - drm_plane_cleanup(p); -} - static int atmel_hlcdc_plane_init_properties(struct atmel_hlcdc_plane *plane) { const struct atmel_hlcdc_layer_desc *desc = plane->layer.desc; @@ -1003,7 +993,7 @@ static void atmel_hlcdc_plane_atomic_destroy_state(struct drm_plane *p, static const struct drm_plane_funcs layer_plane_funcs = { .update_plane = drm_atomic_helper_update_plane, .disable_plane = drm_atomic_helper_disable_plane, - .destroy = atmel_hlcdc_plane_destroy, + .destroy = drm_plane_cleanup, .reset = atmel_hlcdc_plane_reset, .atomic_duplicate_state = atmel_hlcdc_plane_atomic_duplicate_state, .atomic_destroy_state = atmel_hlcdc_plane_atomic_destroy_state,
