[PATCH v2 0/3] 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.

Changes since v1:

 * rewrite the drivers as an MFD

 * rewrite the irq part of the gpio driver to use GPIOLIB_IRQCHIP 

 * cleanup the I/O interface 

 * various fixes and cleanps: check received message sizes before
   parsing, error handling for usb_submit_urb, check URB status, use
   single bit manipulation functions instead of bitmap_*, move
   GFP_KERNEL URB submit away from under lock
