Hi,
the change in the patch looks good to me.
However, it does not appear to be a networking patch,
so I think you have sent it to the wrong place.
With reference to:
$ ./scripts/get_maintainer.pl drivers/gpu/host1x/fence.c
Thierry Reding <thierry.reding@gmail.com> (supporter:DRM DRIVERS FOR NVIDIA TEGRA)
David Airlie <airlied@gmail.com> (maintainer:DRM DRIVERS)
Daniel Vetter <daniel@ffwll.ch> (maintainer:DRM DRIVERS)
Sumit Semwal <sumit.semwal@linaro.org> (maintainer:DMA BUFFER SHARING FRAMEWORK)
"Christian König" <christian.koenig@amd.com> (maintainer:DMA BUFFER SHARING FRAMEWORK)
dri-devel@lists.freedesktop.org (open list:DRM DRIVERS FOR NVIDIA TEGRA)
linux-tegra@vger.kernel.org (open list:DRM DRIVERS FOR NVIDIA TEGRA)
linux-kernel@vger.kernel.org (open list)
linux-media@vger.kernel.org (open list:DMA BUFFER SHARING FRAMEWORK)
linaro-mm-sig@lists.linaro.org (moderated list:DMA BUFFER SHARING FRAMEWORK)
And https://lore.kernel.org/dri-devel/39c44dce203112a8dfe279e8e2c4ad164e3cf5e5.1666275461.git.robin.murphy@arm.com/
I would suggest that the patch subject should be:
[PATCH] gpu: host1x: Remove redundant null check before kfree
And you should send it:

Apologies for the mistake... I'll resend it to the correct place.
Thanks for your reminder, anyway.
Best,
