Submodule commits are not allowed. Please run:
git status --ignore-submodules=dirty
and/or:
git diff-index --cached --ignore-submodules=dirty HEAD
... to see what's in your index.
If you're really and truly trying to roll the version of a submodule, you should
commit the new version to DEPS, instead.
