I wish Dmitry took the opportunity to move this driver to the gpiod
API, especially since doing so would be trivial for this driver. Not a
critical requirement though, the present patch is already an
improvement. But if you want to do that last step, please have a look
at Documentation/gpio/consumer.txt and the "Platform Data" section of
Documentation/gpio/board.txt.
