This patch changes the order in the drivers makefile, so iommu/ subsystem is linked before gpu/ subsystem. That way, if the gpu and iommu drivers are compiled inside the kernel image (not as modules), the correct order of device loading is still maintained (iommu module is loaded before gpu module).
