Subject: [bluez PATCH v2] avrcp: include all player settings in notif event

According to AVRCP 1.6.2 spec section 6.7.2 table 6.39, all player
application settings should be returned to the CT and let CT to
determine which settings have changed. Currently bluez only returns
the changed attribute instead. This patch also addresses a potential
issue on which the number of application settings mismatches with
the actual number returned.

Has there been any new version? It looks like CI has caught some

If so, that has been resolved in v2.
