Okay, these 4 patches fix the issue, but they also refactor the code and
so a lot more. They are not suitable for stable kernels, so to just fix
the issue I take the small patch I extracted from yours and posted
previously. I retains your authorship, hope that is fine with you.

You can rebase these patches on-top of that minimal fix.
