From: Victor Toso <me@xxxxxxxxxxxxxx> Explanation on this mutex in commit 4eea5f3 in 2016-03-24 by Kirill Moizik <kmoizik@xxxxxxxxxx>. This is missing in the polkit code path and its the major difference with _open_device_async_cb() callback. Next patch will remove _open_device_async_cb() to keep code path for access control mandatory there so add this lock/unlock now with some context on why.
