No, platform_device_add which is called by platform_device_register*
will take care of adding the resources - but only if if's told about them
which the old driver didn't.
Also, in case of a resource conflict a device should not be added at all but
exactly that is what the old code did. A resource conflict would have been
caught by the platform_driver probing code well too late.

Good point - I was already wondering if something like that does exist.
What's left over of the swarm driver way too much looks like it can be
squeezed into some sort of template.
