There is a minor fault about ACPI enumerated I2C devices with their modalias
attribute. Now modalias is set by device instance not by hardware ID.
For example "i2c:INTABCD:00", "i2c: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.
IMO, this is not the proper fix for the modalias problem because ACPI
enumerated I2C device may have compatible ids.
Instead, we should export all the compatible ids as the modules alias of
the ACPI enumerated I2C device.
can you please take a look at the patch I sent out earlier?

I see. This makes sense as it avoids that same device has two different
modaliases from both acpi and other subsystem.
How about modalias nodes in sysfs, should they also reflect what is
matching uvent?
