From: Jan Kardell <[email protected]> 3.12-stable review patch. If anyone has any objections, please let me know.
=============== commit baa3c65298c089a9014b4e523a14ec2885cca1bc upstream. Since AI lines could be selected at will (linux-3.11) the sending and receiving ends of the FIFO does not agree about what step is used for a line. It only works if the last lines are used, like 5,6,7, and fails if ie 2,4,6 is selected in DT.
