net-caif: add CAIF generic caif support functions

Hi Dmitry,

The patch 15c9ac0c80e3: "net-caif: add CAIF generic caif support functions" from Mar 30, 2010, leads to the following static checker warning:

	net/caif/cfpkt_skbuff.c:289 cfpkt_setlen()
	warn: bad indenting.

net/caif/cfpkt_skbuff.c
275 int cfpkt_setlen(struct cfpkt *pkt, u16 len) 276 {
277 struct sk_buff *skb = pkt_to_skb(pkt);
278
279
280 if (unlikely(is_erronous(pkt)))
281 return -EPROTO;
282
283 if (likely(len <= skb->len)) {
284 if (unlikely(skb->data_len))
285 ___pskb_trim(skb, len);
286 else
287 skb_trim(skb, len);
288
289 return cfpkt_getlen(pkt);

I don't think curly braces were intended here around the else, but soon the static checker will suggest them. I wouldn't be surprised if some already do.

   290          }
   291  
   292          /* Need to expand SKB */
   293          if (unlikely(!cfpkt_pad_trail(pkt, len - skb->len)))
   294                  PKT_ERROR(pkt, "skb_pad_trail failed\n");
   295  
   296          return cfpkt_getlen(pkt);
   297  }
