When backport the upstream commit to the internal LTS kernel version,
we usually use the following description [1] [2]:
[ Upstream commit cc6528bc9a0c901c83b8220a2e2617f3354d6dd9 ]
or
commit c51f8f88d705e06bd696d7510aff22b33eb8e638 upstream.
We use checkpatch.pl before auto build and there exists auto build
failure due to the following checkpatch error:
ERROR: Please use git commit description style 'commit <12+ chars of sha1> ("<title line>")' - ie: 'commit cc6528bc9a0c ("r8169: fix potential skb double free in an error path")'
#6:
[ Upstream commit cc6528bc9a0c901c83b8220a2e2617f3354d6dd9 ]
or
ERROR: Please use git commit description style 'commit <12+ chars of sha1> ("<title line>")' - ie: 'commit c51f8f88d705 ("random32: make prandom_u32() output unpredictable")'
#6:
commit c51f8f88d705e06bd696d7510aff22b33eb8e638 upstream.
We can use "--ignore GIT_COMMIT_ID" to avoid this checkpatch
error, but I think it is better to modify the check rule of
checkpatch. When there exists "Upstream" or "upstream" in the
commit line, it seems no need to do more check.

Internal to what?
If it's your own internal build system, I think you should
keep your own local patch to checkpatch.
I don't see why the kernel version should accept it.
Is this style used by anyone else?

AFAIK, this style is only used in the stable tree, for example:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=linux-5.9.y&id=c68a9ca7ca33f1020cca97e4e935c2154bec37c7

Greg?/Sasha?

Is this in your scripts?
Is this something you want/use?

My scripts put this into a patch when applying it to the stable tree,
and so do Sasha's. I don't know why checkpatch would care about this as
that's not used for this workflow at all.

I wouldn't use it, and I doubt anyone else would.
