/**
* struct vimc_stream - struct that represents a stream in the pipeline
*
* @pipe: the media pipeline object associated with this stream
* @ved_pipeline: array containing all the entities participating in the
* stream. The order is from a video device (usually a capture device) where
* stream_on was called, to the entity generating the first base image to be
* processed in the pipeline.
* @pipe_size: size of @ved_pipeline
* @kthread: thread that generates the frames of the stream.
*
* When the user call stream_on in a video device, struct vimc_stream is
* used to keep track of all entities and subdevices that generates and
* process frames for the stream.
