From: Ian Molton <ian.molton@xxxxxxxxxxxxxxx> Videobuf2 complains about buffers that are still marked ACTIVE (in use by the driver) following a call to stop_streaming(). This patch returns all active buffers to state ERROR prior to stopping. Note: this introduces a (non fatal) race condition as the stream is not guaranteed to be stopped at this point.
