There are two related topic:

1. A null pointer dereference bug:

    https://lkml.kernel.org/r/20251118021047.uyldr7aay6fb5evt@master
    https://lkml.kernel.org/r/20251117012239.lqm33uu4vl4y5zqc@master
    https://lkml.kernel.org/r/337CD281-F5B3-47FE-82C3-ECB236450F60@nvidia.com

This three mail are related to the bug, which is fixed in :

    http://lkml.kernel.org/r/20251119235302.24773-1-richard.weiyang@gmail.com

Currently looks good, and will do backport when necessary.

2. A further cleanup attempt:

    https://lkml.kernel.org/r/136E8B1C-3352-412C-8038-627F5CC8A112@nvidia.com

This one is the related mail.

I proposed one version in 

    http://lkml.kernel.org/r/20251114075703.10434-1-richard.weiyang@gmail.com

But it is not proper, will do follow up work later.
