The commit added a bridge subdev in addition to the video node, which is generally a better description of the CSI hardware and also a necessity to support the ISP data flow. Maybe your userspace application is not configuring the bridge media block = with the right format, which results in a mismatch? Some work was started to achieve automatic format propagation, perhaps it would be enough to solve your issue.
