  firewire: core: fill model field in modalias of unit device for legacy layout of configuration ROM (2024-01-10 18:37:13 +0900)

----------------------------------------------------------------
firewire updates for 6.8

This update includes the series of changes related to device attributes,
as well as slight code refactoring.

Some old devices are recognized to have legacy layout of configuration ROM.
They have an inconvenience that FireWire subsystem adds no attributes for
vendor information to corresponding devices. The main purpose of this
update is to rectify the inconvenience.

We have a slight concern about regression. The update changes the value of
modalias for the unit devices by populating its model field, which was
previously left as zero in the case. I've assessed the potential impact of
this change and anticipate it to have minimal concern for both the kernel
and user lands. The change is enough acceptable.
