Yes, owning such a device (non-UAC3 with multiple configurations) was
the motivation for investigating in the first place (since it was
broken on v4.20.0 and v4.20.1). So the proposed patch is tested
against it.

In fact, I only discovered ff2a8c532c14 ("usbcore: Select only first
configuration for non-UAC3 compliant devices") when preparing to send
in the patch (it's not in any released kernel yet)
