Thanks Joe, this is very useful for me. I seem to have one false alarm
though:

drivers/net/wireless/ath/ath6kl/txrx.c:464: CHECK: Alignment should
match open parenthesis

This is with patches I haven't sent yet so line numbers most likely
don't match, but the code in question is this:

	if (!IS_ALIGNED((unsigned long) skb->data - HTC_HDR_LENGTH, 4) &&
	    skb_cloned(skb)) {

Apparently the cast "(unsigned long)" causes the false alarm as when I
remove it I don't see the warning anymore.
