I am not proposing any automatic mechanism for killing the audio in the 
my hdmi codec patch set. I am merely providing the means for the video 
driver to gracefully abort the audio stream if the driver decides it can 
not support it any more.

For external HDMI encoders that is hardly ever needed, since the CPU DAI 
is usually the bit- and frame-clock master in those cases. The CPU DAI 
can go on banging the bits even if the encoder isn't listening. So we 
can drop the abort_cb() that if it still annoys you after this explanation.

Best regards,
