Mainline/master won't work in most of the cases. You need to rebase your
work on maintainer's tree. This is sometimes tricky, so usually it's
enough to base on linux-next.

In this case, either use linux-next or for-next branch of my tree:
https://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux.git/
