drm/i915: Don't unset intel_connector->mst_port
Currently we set intel_connector->mst_port to NULL to signify that the MST port has been removed from the system so that we can prevent further action on the port such as connector probes, mode probing, etc. However, we're going to need access to intel_connector->mst_port in order to fixup ->best_encoder() so that it can always return the correct encoder for an MST port to prevent legacy DPMS prop changes from failing. This should be safe, so instead keep intel_connector->mst_port always set and instead just check the status of drm_connector->regustered to signify whether or not the connector has disappeared from the system. Changes since v2: - Add a comment to mst_port_gone (Jani Nikula) - Change mst_port_gone to a u8 instead of a bool, per the kernel bot. Apparently bool is discouraged in structs these days Changes since v4: - Don't use mst_port_gone at all! Just check if the connector is registered or not - Daniel Vetter Signed-off-by: Lyude Paul <lyude@redhat.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: stable@vger.kernel.org Link: https://patchwork.freedesktop.org/patch/msgid/20181008232437.5571-4-lyude@redhat.com (cherry picked from commit 6ed5bb1fbad34382c8cfe9a9bf737e9a43053df5) Signed-off-by: Rodrigo Vivi <rodrigo.vivi@intel.com>
