Now modalias is set by device instance not by hardware ID. For example "spi:INTABCD:00", "spi:INTABCD:01" etc. This means each device instance gets different modalias which does match with generated modules.alias. Currently this is not problem as matching can happen also with "acpi:INTABCD" modalias. Fix this by using ACPI hardware ID.
