olpc_dcon is the only remaining i2c client device driver declaring I2C_CLASS_DDC support after the legacy eeprom driver has been removed. olpc_dcon is only used on olpc devices, connected to an i2c adapter driven by scx200_acb. This adapter driver declares support for I2C_CLASS_HWMON and I2C_CLASS_SPD. Therefore we can safely drop I2C_CLASS_DDC support in olpc_dcon. That's the last step before I2C_CLASS_DDC can be removed in general. This patch is solely based on documentation, and I don't have an olpc device for testing. Therefore some testing would be appreciated before patch is applied.
