Is this resolved now with the PR or do we still have warnings.

Is this resolved now with the PR or do we still have warnings.

Two warnings, both indicated signed / unsigned miss match at the moment when issue was reported, both fixed. Not sure if something came up in the meantime?

[crutkas]

Let’s mark resolved then if the PR solved that issue and then if something else pops up we file a new issue
