This converts the per-board modules to platform drivers for a device created by in main platform setup. These drivers call snd_soc_register_card() directly instead of going via a "soc-audio" device and the corresponding driver in soc-core.
Signed-off-by: Mans Rullgard mans.rullgard@linaro.org --- This version uses a table to assign the device name in omap_init_audio(). It is certainly less ugly than the previous patch.
