[libcamera-devel] [PATCH v2 2/2] libcamera: pipelines: ipu3: Simplify error bail out path on start()

[Umang Jain]

On the bail out path, always ensure that ImgU and CIO2 are stopped
before freeing the buffers. V4L2VideoDevice class guarantees that
calling stop() without having to call start() is harmless, hence use
this guarantee to simplify error paths.
