However, apart from this patch there are three other places in arch/arm/mach-imx/ where dma_declare_coherent_memory() is called after calling platform_device_register_full(). Perhaps this is enough reason to extend platform_device_register_full(). It would be great to get some more feedback on this and also if there is a reliable way to check if a device is already added.
