In the current implementation, there is a very small window for the audio side to safely signal the hdmi_code_shutdown() before the clocks are disabled. Add some synchronization between the DP display and DP audio module to safely disable the clocks to avoid unclocked access from audio side. In addition, audio side can open the sound card even if DP monitor is not connected. Avoid programming hardware registers in this case and bail out early. Changes in v4: - removed some leftover prints Changes in v5: - fix crash when user tries to play audio in suspended state Changes in v6: - rebased on top of latest patchset of dependency Signed-off-by:
