The Broadcom AFBR-S50 time-of-flight sensor driver double-completes an RTIO submission when sensor data evaluation fails. In data_ready_work_handler() (drivers/sensor/broadcom/afbr_s50/afbr_s50.c), a non-STATUS_OK return from Argus_EvaluateData() calls handle_error_on_result(), which finalises the request with rtio_iodev_sqe_err(), but execution then fell through to the tail of the function and finalised the very same struct rtio_iodev_sqe a second time with rtio_iodev_sqe_ok(). Unlike the other error branches in the same function, this one did not return. Both completion helpers reach rtio_executor_done() in subsys/rtio/rtio_executor.c, which returns the submission to the pool via rtio_sqe_pool_free() and, for streaming (multishot) submissions, also releases the RX buffer with…
