Parport registers tables under these paths: dev/parport/default/ dev/parport/PORT/ dev/parport/PORT/devices/ dev/parport/PORT/devices/DEVICE/ Nothing else is registered below dev/parport/PORT/devices/DEVICE/ and I assume device names are unique (if they are not this patch is invalid), so we can skip name checks for the 'DEVICE' directory. This will have a positive performance impact when there are many devices registered on the same port.
