Forgive me if I am being dense, but I still don't see how that works.
The current code:
return (strncmp(pdev->name, drv->name, BUS_ID_SIZE) == 0);
will only return 1 if pdev->name and drv->name are _identical_ for the first 20 bytes. Which "floppy" and "floppy0" are not.
Could it be that all current platform devices are initially named as "<name>" and the instance number is only appended after matching has been done?
Later, Kenn
