The way in which the platform device is created in this file seems to
have a problem.  The mainstone_wm8753_probe() function (along
everything else after that point) seems to expect that the platform
device will be encapsulated in a struct snd_soc_machine, but this
doesn't seem to be the case since you are instantiating the device
with platform_driver_probe().  Am I missing something?
