The link to patchset is: \nhttps://patchwork.kernel.org/cover/10948831/\nSince this patchset is old, I will follow this patchset (Introduce\nmultiple streams to the pipeline handler) with Niklas' patch rebased on\nthe current media-tree so that it becomes easy to test my patchset.\n\nI tested this patchset with cam.
