trivia:

My preference for style here is to have the format
and args on one line when it fits and separate
the format and args lines when they don't.

	WARN(1, "netdevice: %s%s\n" format,
	     netdev_name(dev), netdev_reg_state(dev), ##args)

Unrelated:  maybe it'd be better to change the '\n' to ": "
