If the gadget hardware drivers were registering the device with a
gadget_bus_type, you could still enforce the only one protocol
rule by binding every protocol to every device in that bus type.
And you'd have to rewrite all the gadget drivers

Not a problem, but an observation: Most new code uses work queues instead
of tasklets these days, which gives you more predictable real time
latencies.
If you don't have a specific reason to prefer a tasklet, just use
a workqueue here.

No. That isn't what Arnd was concerned about. He noted that even if

No, you've got it exactly backward. There can be multiple protocol
