Sorry, but editing a patch directly is too risky.  You shouldn't do
that.  This does not apply anymore because there now is a line missing
here...

This is nitpicking, but it needs to be correct for the patches to be
accepted.

Before resubmitting, I suggest:

 - check all the patches with scripts/checkpatch.pl
 - fix absolutely all ERRORs.  You may ignore some WARNINGs if there are
   good reasons to do so (e.g the 80 character limit)
 - mail all patches to yourself, and save as you receive them
 - apply the received patches to a clean net-next based branch using
   "git am <patch>"
 - verify the result (build it after each patch is applied and play with
   related config options to make sure nothing breaks)

Also please note that net-next is currently closed due to the merge
window being open: http://www.spinics.net/lists/netdev/msg242161.html

I don't know exactly what the policy wrt new drivers is, but you can
assume that David is pretty busy with the stuff he already has queued.
So it is better to hold this work until after v3.11-rc1 is out and David
announces that he has opened net-next again.

And I also believe you should include your final patch to cdc_ncm.c as
part 3/3 of this series.  Otherwise the ordering and dependencies are
not clear.  That patch can be applied on it's own, but it won't make any
sense to do so.  Better make that clear.
