According to the V4L2 API, the VIDIOC_STREAMON ioctl should return EPIPE if there is a format mismatch in the pipeline configuration. As the .vidioc_streamon in the v4l2_ioctl_ops usually forwards the error caused by the v4l2_subdev_link_validate_default (if it is in use), it should return -EPIPE when it detect the mismatch. When an entity is connected to a non enabled link, media_entity_pipeline_start should return -ENOLINK, as the link does not exist.
