maybe something like:

#define dev_ratelimited_level(dev, level, fmt, ...)
do {
	static DEFINE_RATELIMIT_STATE(_rs,				\
				      DEFAULT_RATELIMIT_INTERVAL,	\
				      DEFAULT_RATELIMIT_BURST);		\
	if (__ratelimit(&_rs))						\
		dev_##level(fmt, ##__VA_ARGS__);			\
} while (0)

#define dev_emerg_ratelimited(dev, fmt, ...)				\
	dev_ratelimited_level(dev, emerg, fmt, ##__VA_ARGS__)
#define dev_alert_ratelimited(dev, fmt, ...)				\
	dev_ratelimited_level(dev, alert, fmt, ##__VA_ARGS__)
#define dev_crit_ratelimited(dev, fmt, ...)				\
	dev_ratelimited_level(dev, crit, fmt, ##__VA_ARGS__)
#define dev_err_ratelimited(dev, fmt, ...)				\
	dev_ratelimited_level(dev, err, fmt, ##__VA_ARGS__)
#define dev_warn_ratelimited(dev, fmt, ...)				\
	dev_ratelimited_level(dev, warn, fmt, ##__VA_ARGS__)
#define dev_notice_ratelimited(dev, fmt, ...)				\
	dev_ratelimited_level(dev, notice, fmt, ##__VA_ARGS__)
#define dev_info_ratelimited(dev, fmt, ...)				\
	dev_ratelimited_level(dev, info, fmt, ##__VA_ARGS__)
#define dev_dbg_ratelimited(dev, fmt, ...)				\
	dev_ratelimited_level(dev, dbg, fmt, ##__VA_ARGS__)
