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.

v2:
- change tag in commit subject of patch 03
- add ack tags
v3:
- fix a compile error in patch 5

The fbdev changes look at least ok so far, so:

I think this refers to patch 5 of the series. Could you please reply
to patch 5 instead of the cover letter with your acked-by so that
patchwork gets it right? Thanks!

Sorry, just looked at where you are in To, not Cc.
So your ack includes patches 6, 9, 10, 13?
