[libcamera-devel] [PATCH 3/8] libcamera: pipeline: ipu3: Reset sequence counts to zero on stop

[Kieran Bingham]

Reset the request sequence counter back to zero when a camera has
stopped, giving each camera run an independent sequence stream.

Signed-off-by: Kieran Bingham <kieran.bingham at ideasonboard.com>

RFC: This again would be perhaps better handled by the base class to
ensure all pipeline handlers handle this in a consistent manner.
