[alsa-devel] ASoC: Amplifier behind codec?

Hi,

I have here an amplifier (MAX9768) between codec output and the speaker, all controlled via I2C. I noticed that other amplifier drivers export a function called *_add_controls(), so the platform glue code can add the amplifier controls to the codec. Now, all drivers working like this use a single static instance of the i2c client, because there doesn't seem to be a connection between the added control elements and the additional i2c client.

Is the above approach still the preferred way of doing this?

Thanks,

Wolfram
