Subject: [PATCH] drm/panel: Add and initialise an orientation field to
|
|
drm_panel
|
|
|
|
Current usage of drm_connector_set_panel_orientation is from a panel's
|
|
get_modes call. However if the panel orientation property doesn't
|
|
exist on the connector at this point, then drm_mode_object triggers
|
|
WARNs as the connector is already registered.
|
|
|
|
Add an orientation variable to struct drm_panel and initialise it from
|
|
drm_panel_init.
|
|
panel_bridge_attach can then create the property before the connector
|
|
is registered.
