Rob made me aware about the fact that the hdmi driver is both
implementing a driver for the i2c controller and now for the hdcp
client and hence doesn't have an i2c_client handle.

So unless this is redesigned to be split in a separate i2c client
driver we probably have to have the ddc functions like this.

I'm fine with this as is for now.

Bjorn
