I thought Greg already said not to use platform_device for this?

Yes I did, which is what I thought this whole "use MFD" was supposed to
solve.  Why is a platform device still being used here?

Looks like when mfd creates the 'multi' devices it creates them as
platform_devices

/*
 * Given a platform device that's been created by mfd_add_devices(), fetch
 * the mfd_cell that created it.
 */
static inline const struct mfd_cell *mfd_get_cell(struct platform_device *pdev)
