Comment 16 for bug 1725190

The patches do not have to get accepted upstream, the requirement is that they're available in the latest development series - so for bionic.

So, if for this bug to be fixed the plano patches are required, the steps should be:
 * Uploading the patches to modemmanager bionic
 * The patches get backported to zesty modemmanager
 * Xenial gets a zesty backport of modemmanager with the patches

If the patches aren't needed instantly, I can sponsor a quick backport of the current zesty package to xenial if needed (e.g. without any new patches).
