[pulseaudio-discuss] [PATCH next v1 12/13] bluetooth: Call setup_stream() manually

[Mikel Astiz]

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

Do not call setup_stream() automatically inside bt_transport_acquire().
Instead, the caller is responsible to use both functions as necessary.

As a first trivial step, setup_stream() is now called manually after
all calls to bt_transport_acquire(u, TRUE), with the exception of
setup_transport() where the thread is still about to start and thus
setup_stream() will be called later on from thread_func().
