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.

Are we in a hurry here, i.e. does it block further development of the
i801 smbus driver? My gut feeling says the patches should rather go via
drm and fbdev trees, but I may be convinced otherwise.

We're not in a hurry. It's just my experience with patch series' affecting
multiple subsystems that typically the decision was to apply the full
series via one tree. Also to avoid inquires from maintainers like:
Shall I take it or are you going to take it?
Of course there may be different opinions. Please advise.

Ok, then this turns out to be a negotation thing between the drm/fbdev
maintainers and me. I *can* take all the patches, of course. But since
the number of patches touching the non-i2c subsystems is high, I'd like
to hear their preference, too.

I don't have a preference if you would prefer to take these via i2c.

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.
