2017-01-09	i2c: Allow I2C devices to NAK start events	Corey Minyard	1	-4/+9
	Add a return value to the event handler. Some I2C devices will NAK if they have no data, so allow them to do this. This required the following changes: Go through all the event handlers and change them to return int and return 0. Modify i2c_start_transfer to terminate the transaction on a NAK. Modify smbus handing to not assert if a NAK occurs on a second operation, and terminate the transaction and return -1 instead. Add some information on semantics to I2CSlaveClass.

2016-10-24	i2c: Add asserts for second smbus i2c_start_transfer()	Corey Minyard	1	-3/+9
	Some SMBus operations restart the transfer to convert from write to read mode without an intervening i2c_end_transfer(). The second call cannot fail, so the return code is unchecked, but this causes Coverity to complain. So add some asserts and documentation about this.
