Some of the platform devices rely on the name of their driver to match with. In the current implementation, if platform id table is needed, they have to add the name to the platform id table which sounds alogical. The patch adjustes the logic of the id table matching to make sure we will fall-back to match by the driver name. This will make it similar to the DT or ACPI cases.
