This does not need to be marked packed, since it is never embedded in another
structure.

It's enoug
Some GPIO chips (e.g. the DLN2 USB adapter) have blocking get/set
operation but do not need a threaded irq handler.

This patch adds support for the Diolan DLN-2 I2C master module. Due
to hardware limitations it does not support SMBUS quick commands.

This patch adds GPIO and IRQ support for the Diolan DLN-2 GPIO module.
Information about the USB protocol interface can be found in the
Programmer's Reference Manual [1], see section 2.9 for the GPIO
module commands and responses.

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 v4:
* Add a new gpiolib chip flag to allow blocking chips with non threaded
IRQ handlers
* MFD: set GPLv2 as licens
Previously only the ACPI PM domain was supported by the i2c bus.
Let's convert to the common attach/detach functions for PM domains,
which currently means we are extending the support to include the
generic PM domain as well.

I defer the patch series for now. Maybe we should talk about it at our
