Mark, our issue here is that we have a driver tied to a device that is
an HDMI encoder. Obviously, we'll want to register into DRM, which is
what we were doing so far, with the usual case where at remove /
unbind time, in order to free the resources, we just retrieve our
pointer to our private structure using the device's drvdata.

Now, snd_soc_register_card also sets that pointer to the card we try
to register, which is problematic. It seems that it's used to handle
suspend / resume automatically, which in this case would be also not
really fit for us (or rather, we would need to do more that just
suspend the audio part).

There's a drvdata field in the snd_soc_card for cases like this - would
that work for you?
