Subject: [PATCH BlueZ v2] mesh: Set global bus earlier
Date:   Mon, 25 Jul 2022 10:05:49 +0200

Some io implementations might want to either make calls to other D-Bus
services, or provide additional objects/interfaces that allow
applications to fine-tune their operation, so allow them to use the bus
even before initializing mesh D-Bus interfaces.
