[PATCH v9 0/4] mfd: add support for Diolan DLN-2

[Octavian Purdila <octavian.purdila@xxxxxxxxx>]

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
