This series works on the .s_stream, .enable_streams, .disable_streams related code. The main feature introduced here, in the last patch, is adding support for .enable/disable_streams() for subdevs that do not implement full streams support. Additionally we add support for the privacy led when v4l2_subdev_enable/disable_streams() is used. I have tested this on RPi5.
