I also noted several checkpatch.pl issues with your patches, so please fix those up as well. Can you please fix up your patches based on my tree: git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/queue.git This my queue of all community patches against the Intel LAN drivers and will be where I queue up your patches while they are under review and testing.
