Thanks for sending new version of this patch.

Just a note for next time, as explained in this page:
	http://dpdk.org/dev#send
it's a good practice do put a changelog after the 3 dashes. It allows to us to understand why this new version is for.

In this case, the changelog should be:

changes in v2:
- fix code style according to checkpatch.pl

Thanks
