This patch series adds a flag to the Acquire method in the Media API, in order to fix the race condition described in patch v1 3/4.

v1 tries to follow the proposal from Luiz by avoiding changes in the internal callbacks, and instead using the state information available in struct media_transport.

Patch v1 4/4 needs careful review since the replacement of the in_use flag is not trivial.

From original patch:

This patch reopens the discussion started by the thread "when is acquire
ok to call". The race condition seems to be real (even thought difficult
to reproduce), and I couldn't think of any approach to solve this
without altering the Media API.

Mikel Astiz (4):
  media: Watch A2DP sink-source state changes
  media: Add boolean playing field to transport
  media: Extend media API with optional acquire
  media: Remove transport in_use flag
