Subject: [BlueZ PATCH v2 3/3] shared/shell: Fix not releasing prompt

From: Luiz Augusto von Dentz <[email protected]>

This fixes not releasing prompt when queueing a line to be executed
since it can be considered as user input if the init script is
attempting to enter it as response to prompt input.

Subject: [BlueZ PATCH v2 2/3] client/player: Fix crash when RegisterEndpoint fails

From: Luiz Augusto von Dentz <[email protected]>

If RegisterEndpoint fails when there are multiple adapters it would
attempt to free the same endpoint multiple times.
