553 o correctly extends the timeout depending on the size of all
554 queued messages for both transmit and receive
555 o will not continue with receive if transmit times out
556 o ensures that the error callback is done for all queued tx

559 the callback, and does not overwrite an earlier error
560 o logic in i2c_probe now correct
