PS10, Line 115: 	.acpi_inject_dsdt = chromeos_dsdt_generator,
It turns out there is really no need for the device node after all and we could call chromeos_dsdt_generator directly. Also this and some intel/xeon are the only users of .acpi_inject_dsdt so there might be chance to discuss if we really need this.
