That's not really possible to do via checkpatch.
checkpatch is neither a compiler nor a programmer.

There are _many_ patterns that a person (or maybe

All of the dev_<level> uses in this file/module
should be inspected and possibly converted to
netdev_<level> or netif_<level>.  This could change
and improve the output message logging.
