1515 o correctly extends the timeout depending on the size of all
1516 queued messages for both transmit and receive
1517 o will not continue with receive if transmit times out
1518 o ensures that the error callback is done for all queued tx
1520 o correctly detects both tx and rx timeouts, only delivers one to
1521 the callback, and does not overwrite an earlier error
1522 o logic in i2c_probe now correct
1523 - add "vprintf()" function so that "panic()" function can be
