Hi Bing.

There's an issue with the checkpatch patch.
It doesn't always work correctly when there
are consecutive parenthesis.

Kalle Valo showed an example that fails:

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

I have a tentative fix here, but I'm waiting on
Andy Whitcroft to give some guidance on how best
to fix it given a minimum perl version of 5.10.

The proposed patch doesn't work with perl versions
less than 5.10 and there is at least one person
that still uses 5.8.
