 That seems to be missing from this patch, and it means that when the

It looks like there's been a bug introduced in this patch (which wasn't
in my original).

I also disabled the writing to REG_ENA_AP in the DPMS off path as well,
which clears this register.

That seems to be missing from this patch, and it means that when the
display is placed into DPMS-off mode, the audio inputs are disabled,
never to be re-enabled.  There is no need to disable the audio input
in DPMS-off mode.

From: Russell King 
Subject: [PATCH] drm/i2c: Fix broken TDA998x audio

In patch "drm/i2c: tda998x: add video and audio input configuration" in
its original version, disabling the audio input port was removed.  The
version which was submitted for merging had this change deleted, which
results in audio being non-functional.  Fix this by removing the write.
While here, update the comment too.
