Care to show me what the diff stat for a non devlink driver would look
like? Just keep in mind this taint is 1 line addition. Granted, if we
can use SmPL grammar to automate addition of an initial framework to a
driver that'd be great, but since the device addition is subsystem
specific (device_add() and friends), I don't suspect this will be easily
