    is always false [-Wtautological-constant-out-of-range-compare]

eef8f25a44 kinetis: i2c: Handle ARBL flag in master mode. 
The ARBL flag signals that bus master arbitration has been lost.
This may occur if devices on the bus misbehave, or in a multi-master
situation, or if devices are not powered and pull the SDA line down, or
if the communication wires are disconnected while communicating.
