Wait, what? Why is this being autosel'd?
Stable trees try to pick up device enablement patches (such as patches that add PCI IDs). I suppose that AUTOSEL get pretty eager to grab those.
Is it so common that old drivers will work with new HW with just a PCI_ID update?
I would have guessed that is the minority situation
So keep in mind that a lot of it is not brand new HW, but rather same HW repackaged by a different vendor, or HW that received minor tweaks but where the old driver still works.
I suppose it's more common in the USB ID world these days, so I guess I'll give PCI IDs a closer look next time.
