Subject: [PATCH v4 07/20] drivers/gpu/drm: remove I2C_CLASS_DDC support
Date:   Mon, 20 Nov 2023 22:46:10 +0100

After removal of the legacy EEPROM driver and I2C_CLASS_DDC support in
olpc_dcon there's no i2c client driver left supporting I2C_CLASS_DDC.
Class-based device auto-detection is a legacy mechanism and shouldn't
be used in new code. So we can remove this class completely now.

Preferably this series should be applied via the i2c tree.
