I would prefer the more frequently used macro style:
#define DBG(fmt, args...) \
do { if (DBG_VAR & 1) printk(KERN_DEBUG DBG_PREFIX ": %s: " fmt, \
__func__, ##args); } while (0)
#define DBG_FRAME(fmt, cf) \
do { if (DBG_VAR & 2) can_debug_cframe(fmt, cf); } while (0)
#define DBG_SKB(skb) \
do { if (DBG_VAR & 4) can_debug_skb(skb); } while (0)
