If timeout error occurs in the i2c transfer then it was dumping warning
of call stack.

Remove the warning dump as there is may be possibility that some slave
devices are busy and not responding the i2c communication.

The patch is generated based on discussion happen between Stephena and
Wolfram on the patch:
