Why not ? Do you have a better idea ?

What I actually need is a way to unbdind a specific device, identified
by bus name and device name. The problem to be solved here is dropping
devices that have been enumerated in a bad way by firmware (ACPI in this
case), and then recreating it in a clean, consistent way.

If there was a variant of bus_find_device_by_name() which takes the name
instead of ptr to the bus, that would also be okay for me.
