A previous cleanup patch accidentally broke some conditional expressions by replacing the safe "do {} while (0)" constructs with empty macros. gcc points this out when extra warnings are enabled: drivers/net/wireless/ath/ath9k/hif_usb.c: In function 'ath9k_skb_queue_complete': drivers/net/wireless/ath/ath9k/hif_usb.c:251:57: error: suggest braces around empty body in an 'else' statement [-Werror=empty-body] 251 | TX_STAT_INC(hif_dev, skb_failed); Make both sets of macros proper expressions again.
