Since the provision of a struct device for the CODEC is now mandatory we can use container_of() to locate the struct i2c_client and struct spi_device for relevant devices, removing the need to manually set it in each driver.
A further patch will automate selection of the control type based on the bus_type of the struct device, further reducing the amount of driver code required.
