Currently when the RC Core is enabled (reachable) core code located in cec_register_adapter() attempts to populate the RC structure with a pointer to the 'parent' passed in by the caller. Unfortunately if the caller did not specify RC capability when calling cec_allocate_adapter(), then there will be no RC structure to populate. This causes a "NULL pointer dereference" error.

Add support for CEC notifiers, which is used to convey CEC physical address information from video drivers to their CEC counterpart driver(s). Based on an earlier version from Russell King: https://patchwork.kernel.org/patch/9277043/ The cec_notifier is a reference counted object containing the CEC physical address state of a video device. When a new notifier is registered the current state will be reported to that notifier at registration time.

2017-04-10[media] v4l: vsp1: Prevent multiple streamon race commencing pipeline earlyKieran Bingham
With multiple inputs through the BRU it is feasible for the streams to race each other at stream-on. Multiple VIDIOC_STREAMON calls racing each other could have process N-1 skipping over the pipeline setup section and then start the pipeline early, if videobuf2 has already enqueued buffers to the driver for process N but not called the .start_streaming() operation yet In the case of the video pipelines, this can present two serious issues. 1) A null-dereference if the pipe->dl is committed at the same time as the vsp1_video_setup_pipeline() is processing 2) A hardware hang, where a display list is committed without having called vsp1_video_setup_pipeline() first Repair this issue, by ensuring that only the stream which configures the pipeline is able to start it.
