This patch series adds support for Diolan USB-I2C/GPIO Master Adapter
DLN-2. Details about device can be found here:

https://www.diolan.com/i2c/i2c_interface.html.

This patch series is against the MFD tree branch
for-mfd-next-v3.19. It does include a gpiolib patch that was merged by
Linus W but it was not yet pulled into Lee's tree.

Changes since v8:

* common: remove result parameter from dln2_transfer as it is not yet
used in this patch set (we will add it later with the i2c change
freq patches); fix comments to wrap to 80 columns instead of 70

* MFD: add two variants for dln2_transfer: dln2_trasfer_rx and
dln2_transfer_tx; use entry instead of new_cb in
dln2_register_event_cb; rename dln2_rx_transfer to
dln2_transfer_complete and add comment about the URB completion,
also move the warning about late/missing responses here;

* GPIO: use dln2_transfer_rx and dln2_transfer_tx where possible

* I2C: use dln2_transfer_rx and dln2_transfer_tx where possible; use
adapter's device instead of platform's device for
dev_err/dev_info/etc prints
