[PATCH BlueZ v3 0/2] Fix source+sink endpoint registration

[Claudia Draghicescu]

Create a broadcast source endpoint using only the local endpoint.
This removes the ambiguity when having registered a local 
broadcast sink and fixes the situation when multiple remote 
endpoints are created when discovering a broadcast source.

[PATCH BlueZ v3 1/2] bap: Fix source+sink endpoint registration

[Claudia Draghicescu]

Fix the case when registering both sink and source endpoints,
the register endpoint method call results in 2 remote endpoints
for each scanned broadcast source.
Remove the need of a remote pac when creating a broadcast stream.
