CC Adrian for comment...
Does anything in the Debian installer rely on a specific device name
suffix in /sys/bus/platform/devices/ ?
On Atari, atari-falcon-ide does not have a suffix, but on Q40, it would
get suffix .0 or .1 depending on what IO base the ISA IDE adapter uses.
Seeing as Q40 support in the atari-falcon-ide has been broken since it
was introduced, this is rather about future installer support than about
inadvertently breaking current code.
Cheers,
Michael

Of course 0 also works, but causes ".0" to be appended to the platform
device's name, visible in e.g. /sys/bus/platform/devices/.
That seems desirable to me.
Why would it be desirable?
IMHO this is an unneeded change which is visible in userspace.
Only so what's visible in userspace would be consistent across atari and
q40 (and anything else that happens to instantiate the device in future).
Basically, I don't really understand why id -1 is better than id 0. I've
searched Documentation/device-tree and I still don't understand why a
singleton would need a special bus id.
