+Subject: Revert "Bluetooth: btusb: Fix quirk for Atheros 1525/QCA6174"
+
+From: Hans de Goede <hdegoede@redhat.com>
+
+commit 544a591668813583021474fa5c7ff4942244d654 upstream.
+
+Commit f44cb4b19ed4 ("Bluetooth: btusb: Fix quirk for Atheros
+1525/QCA6174") is causing bluetooth to no longer work for several
+people, see: https://bugzilla.redhat.com/show_bug.cgi?id=1568911
+
+So lets revert it for now and try to find another solution for
+devices which need the modified quirk.
