It's reasonable as any other arrangement. On the other hand, userspace
should understand that the kernel has no policy regarding connector
ordering, which may change on the fly if we ever do hotplug, and do the
sorting itself if it cared about making its legacy clients work better.

The code looks fine so it's a mixture of r-b and a-b.
