Once more I've reflowed your text.  *Please* fix this, it's really
hurting the legibility of your mail.

If you've got a real device and a driver binding to it then you can make
the driver for that device register the DAI from its probe function, no
need for the machine driver to get involved.

Sorry, snd_soc_register_card().  This skips the soc-audio device and
allows the card to be registered from a regular device, meaning you can
do things like pass platform data in sanely and handle multiple boards
in a kernel without machine_is_() faff.
