The build fails with the latest code, unfortunately. This function simply returns an error, as it was changed to a devres allocation some time ago.

Thanks, I have already send a v3 fit for the latest code. But I still think the v2 is useful for the previous code. Actually, this one is suitable for the linux-stable-5.13.9. Therefore, I believe it might be better to apply the v2 to the previous version in order to maintain the consistency.

Sincerely thanks, Jiang
