The ACPI handle of struct i2c_adapter's dev member should not be set, because this causes that struct i2c_adapter to be associated with the ACPI device node corresponding to its parent as the second "physical_device", which is incorrect (this happens during the registration of struct i2c_adapter). Consequently, acpi_i2c_register_devices() should use the ACPI handle of the parent of the struct i2c_adapter it is called for rather than the struct i2c_adapter's ACPI handle (which should be NULL). Make that happen and modify the i2c-designware-platdrv driver, which currently is the only driver for ACPI-enumerated I2C controller chips, not to set the ACPI handle for the struct i2c_adapter it creates.
