Bug description:
This fix is in the v5.3-rc3, and EAON already has this patch by backporting
stable, so
this patch is only for B/D.
[Impact]
After S3, the intel hdmi audio on a dell laptop print the error like below:
[ 2052.030247] snd_hda_codec_hdmi hdaudioC0D2: Unable to sync register
0x2f0d00. -5
And the hdmi audio can't work anymore after this.
[Fix]
For Intel hdmi audio codec, it doesn't need to resume forcibly, because the
i915 side
probably is not ready to let hdmi codec work, since the intel hdmi audio uses
component
framework, let i915 control the hdmi codec.
[Test Case]
Tested on that dell laptops, the hdmi audio doesn't have any issues anymore
after
applying this patch.
[Regression Risk]
Low. We tested this patch on a couple of machines (dell and lenovo).
