Julia Lawall 379883cc67 i2c: constify i2c_adapter_quirks structures
Check for i2c_adapter_quirks structures that are only stored in the
quirks field of an i2c_adapter structure.  This field is declared
const, so i2c_adapter_quirks structures that have this property can be
declared as const also.

the adapter device. This allows the DLN2 bus to work with i2c devices
defined in the device tree.

Laurentiu Palcu db23e5001f i2c: add support for Diolan DLN-2 USB-I2C adapter
This patch adds support for the Diolan DLN-2 I2C master module. Due
to hardware limitations it does not support SMBUS quick commands.

Information about the USB protocol interface can be found in the
Programmer's Reference Manual [1], see section 6.2.2 for the I2C
master module commands and responses.
