drivers: sensors: rtio No error reporting from bus controller to application #81014

Open FlorianWeber1018 opened 2 weeks ago

Is your enhancement proposal related to a problem? Please describe.

If a sensor uses a bus controller with the RTIO there is at the moment no possibility to inform the application if a action of the bus controllers fails. Reporting on success an the moment is implemented with callbacks. If a sqe to the bus controller fails, the callback won´t be called and the sqe to the sensor never produce a cqe.
A example how a sensor driver uses a bus controller with the rtio could be https://github.com/zephyrproject-rtos/zephyr/blob/main/drivers/sensor/adi/adxl362/adxl362_stream.c#L234-L246

Describe the solution you'd like

That the RTIO provides any mechanism to get the cqes of sqes in an asynchrounous way. If we stay on the callback solution for reporting an ok on success at the bus controller, we should at least give the sqes an option to redirect their errors so a different RTIO.

@bperseghetti @jgoppert this likely relates to the issue with rtio and cognipilot as well
