[libcamera-devel] [PATCH 10/10] cam: Don't requeue requests when stopping stream

[Laurent Pinchart]

When stopping the stream all pending requests are cancelled, resulting
in the request completion signal being emitted with the request status
set appropriately. Check the request status in the request completion
slot and skip requeuing the request if it has been cancelled.
