+#define	lrw_get_mac_cb(skb)	((struct lrw_mac_cb *)skb->cb)

Please make this a static inline function.  If the identifier is all lowercase
programmers expect it to be real code not a CPP macro.

+#define	LORAWAN_MODULE_NAME	"lorawan"
+
+#define	LRW_DBG_STR(fmt)	LORAWAN_MODULE_NAME": "fmt
+#define	lrw_info(fmt, ...)	(pr_info(LRW_DBG_STR(fmt), ##__VA_ARGS__))
+#define	lrw_dbg(fmt, ...)	(pr_debug(LRW_DBG_STR(fmt), ##__VA_ARGS__))

Just define "pr_fmt()" appropriately and you don't need to play these kinds
of games.

Set pr_fmt() and call pr_info() and pr_debug() directly.
