Don't know why `check-format (pull_request)` failed again, because latest commit [38a1c73](https://github.com/kamailio/kamailio/commit/38a1c736fa3ebef8827a0f3ef645e7e4...)... PASSED.
yes, the action checks if *all* commits follows the clang-format not the final result. That is why rebase and squash is a better idea in this cases when the first commit is not well formated.
