Bluetooth doesn't reconnect to my headsetup post resume from sleep

[Anmar Oueja]

Steps to repro:

* Cold boot the laptop
* Pair it with bluetooth headset
* Listen to music
* Turn off the headset or turn off the bluetooth on the laptop
* Play music, sound comes out of the laptop speakers
* Turn on the headset back on or the bluetooth on the laptop
* Headset reconnects with the laptop and audio plays from the headset

-- all the above is expected --

* Suspend the laptop
* wait a minute or two for the headset to power down
* Resume the laptop
* Turn on the bluetooth headeset
* It doesn't automatically reconnect to the laptop (not expected behaviour)
* Launch Gnome Settings and select Bluetooth and force the headset to connect
* It connects for 2 seconds then disconnects (not expected behaviour)

The only to get the headset to reconnect again is by restarting the bluetooth.service using systemctl.

Problem seems resolved with bluez 5.48.2 as outlined in this bug: https://bugzilla.redhat.com/show_bug.cgi?id=1534857#c30

The following patches were added to the 5.48 version in Fedora and they did fix the problem. Perhaps worth you adding them as well. Please see https://koji.fedoraproject.org/koji/buildinfo?buildID=1040106 and the bug https://bugzilla.redhat.com/show_bug.cgi?id=1534857
