git0 and gitAUTOINC is the difference you are seeing however when PR is
bumped r0 would change to r0.0 or something which is preceding the
AUTOINC difference and you should be able to upgrade. Although I would
discourage you from using AUTOREVs in release environment. Use locked
SHA values, it will also help you with reproducible builds.
