Bug description:
Since this fix is still in the maintainer's tree, I add the UBUNTU: SAUCE:
prefix in the patch title.
And this patchset is fixing a bug in the oem project, so please merge the
patchset to OEM-B asap.
[Impact]
We often hear the Beep noise when a couple of LENOVO laptops reboot, the
reproduce rate is about 3/10.
[Fix]
make the codec enter D3 before rebooting or poweroff, this can fix the issue.
[Test Case]
Tested on those LENOVO latpops, reboot 50 times, didn't reproduce the
noise issue.
[Regression Risk]
Low. We tested this patch on different lenovo and dell laptops, they
all worked well as bfore.
