Gross. Loses the linkage to device-tree etc... which is useful for audio
especially. You should at least make sure the device node follows for
the target driver to be able to use it :-) I'd like you to sync with
Grant work on that matter if you are going to convert of_devices into
platform_devices.

Cheers,
Ben.
