OK, no problem. I gave it a try myself. Greg, is it OK or did I miss
other parts which can be removed?

Subject: i2c: Kill struct i2c_device_id

I2C devices do not have any form of ID as PCI or USB devices have.
No driver uses "MODULE_DEVICE_TABLE(i2c, ...)" because it doesn't
make sense. So we can get rid of struct i2c_device_id and the
associated support code.
