Correct.  John, you /should/ be able to simply drop the hunk in this
patch that adds platform_data bits.  All you're doing with this patch
is dropping the local declaration of the platform_devices and using
the ones defined in arch/arm/mach-tegra/devices.c.  Setting the
platform_data pointer is not required.
