[pulseaudio-discuss] [RFC next v4 11/16] bluetooth: Support transport auto-release

[Mikel Astiz]

From: Mikel Astiz <mikel.astiz at bmw-carit.de>

With BlueZ 5, if the remote device suspends the audio, the transport
state will change to "idle" and the endpoint is not required to release
the transport, since this could introduce race conditions. Therefore,
ignore the call to pa_bluetooth_transport_release() if the transport is
not acquired any more.
