So maybe add some wrapper that does a pr_info then
a pr_debug for the second and subsequent uses like:

#define pr_info_once_then_debug(fmt, ...)			\
({								\
	static bool __print_once __read_mostly;			\
								\
	if (!__print_once) {					\
		__print_once = true;				\
		pr_info(fmt, ##__VA_ARGS__);			\
	} else {						\
		pr_debug(fmt, ##__VA_ARGS__);			\
	}							\
})
