With this patch that code is probably skipped unconditionally in the
normal case.

Why don't you just set the quirk NO_SET_PROTO for that device? That will
have the same effect.

This makes no sense. The original condition was: "If we are asked not to
set a proto skip this section, otherwise call usbd_set_protocol".

Now it is: "If we are asked not to set a proto, set a proto.".
