+What:   i2c_adapter.id
+When:   June 2011
+Why:    This field is deprecated. I2C device drivers shouldn't change their
+        behavior based on the underlying I2C adapter. Instead, the I2C
+        adapter driver should instantiate the I2C devices and provide the
+        needed platform-specific information.
