thank you for pointing it out, missed the fix in my mailbox and have to reinvent it after stumbling upon the problem.
Could Ard's patch please be picked up by the maintainers, preferably with above Fixes added, so we get this backported onto v5.15 stable...
Right, the bug is quite critical and needs backporting. -- Best wishes, Vladimir
