Hi,

I didn't get around to posting the pull-req before I went on holiday
as there were some comments to address on "docker: reduce noise when
building travis.docker". If there are no other comments I shall roll
the pull request with this.

Alex Bennée (6):
  docker: ensure NOUSER for travis images
  docker: fix dirty/stash detection on some systems
  docker: ignore submodules when checking diff
  docker: docker.py make --no-cache skip checksum test
  docker: don't install device-tree-compiler build-deps in travis.docker
  docker: reduce noise when building travis.docker
