New mail from Cirrus Logic: """" Hi Canonical / Dell team:
We have an update on Ubuntu S3 resume issue. Here is the explanation of the update. We have to re-open this issue as the patch was rejected by the maintainer. However we have another patch, that will fix an issue and it was proposed by the maintainer, implemented, and submitted to mainline. This patch has also been merged by upstream. We need to communicate to the customer that for the next kernel ODM build they have to revert the previous patch and apply a new one: https://patchwork.kernel.org/project/alsa- devel/patch/20211128115558.71683-1-vita...@opensource.cirrus.com/ Thanks, Vitaly Short summary: If the OEM kernel is already code freezed, that’s fine and forget about the new patch. If the OEM kernel is NOT yet code- freezed, you might want to consider reverting the current patch (https://patchwork.kernel.org/project/alsa- devel/patch/20211124181908.50672-1-vita...@opensource.cirrus.com/ ) and apply the new patch ( https://patchwork.kernel.org/project/alsa- devel/patch/20211128115558.71683-1-vita...@opensource.cirrus.com/ ).
