Enable maintainer updates

Please enable maintainer updates so we can push commits into your branch to make collaboration and reviews easier.

Do not force push your branch

Please avoid force pushing to branches that are subject of pull requests. Force pushing breaks maintainer commits in many cases and is very hard (if not impossible) to untangle for backporting.
