** Description changed: - We can't reproduce the hdmi audio issue anymore on the icl laptop even - without disable_power_well=0, and disable_power_well=0 will prevent - the CPU from entering PC10 power state, let us revert this patch. + [Impact] + Two weeks ago, we sent the patch to set disable_power_well=0, this is + because we found sometimes the hdmi audio driver printed out the timeout + errors when accessing the codec. But recently the ODM told us those + machines had some HW or BIOS issues, we can't reproduce the timeout + errors on the new machines anymore even without this patch. And moreover + we need put the CPU into PC10 power state to meet the E-star starndard, + we need to revert this patch. + + [Fix] + Revert the patch. + + [Test Case] + Tested on the new icl laptops, we have not reproduce the timeout errors, + and The PC can enter PC10. + + [Regression Risk] + Low. We have done many tests.
