it's the latest revision in my Github (commit 56911ecbe2ffa5d07f5748ba49ddeb1735b5f30b).

The plus sign (comment from kernel sources):
# append a plus sign if the repository is not in a clean
# annotated or signed tagged state (as git describe only
# looks at signed or annotated tags - git tag -a/-s) and
# LOCALVERSION= is not specified
