So far, only B/OEM-B has this issue, we can't reproduce the issue under
D/OEM-OSP1. Because the urgent schedule of project, let us merge this
sauce patch to OEM-B first, and we will biset to find the real fix
later.
[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]
Skip forcible resume both for analog codec and hdmi codec
[Test Case]
Tested on that 2 dell laptops, the hdmi audio doesn't have any issues anymore
after applying this patch.
[Regression Risk]
Low. This patch only apply to those two Dell machines by system id.
