The bug #989705  is currently closed. It was solved for kernels
version 5.15+ using the patch  from upstream.
This patch  applies to kernel version 5.10.y, too. I used it with a
custom built kernel since it was published .
The author of the patch acknowledged that the patch applies to kernel
version 5.10.y asking me to send it out to the stable mailing list. I
did it, but I did not receive an answer. I tried to peek upstream, but
again no answer.
Therefore, I'm sending this post to ask the debian-kernel mailing list
if it is possibile to cherry pick the patch  to make it land in the
next release of Debian Kernel 5.10.y.
Let me know if I can help in any way. I cannot update bug #989705
because it is currently closed.
Thanks in advance for your attention.
