The file saw a couple of small changes in next-20160923, so I think
this was just unfortunate timing but you used the right tree.

staging can be moving very rapidly at times, so if you want to
be sure to get the right tree of the minute, you can
rebase on top of

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git staging-testing

I usually just base on top of the linux-next of the day, which tends
to work well enough.
