You missed commit 6cbf8b38dfe3 ("i3c: fix uninitialized variable use in
i2c setup") as a fix for this one, as rightfully pointed out by clang:

https://lore.kernel.org/177198114226.2577.15577566399399369654@d14e337afe00/

$ make -skj"$(nproc)" ARCH=x86_64 LLVM=1 mrproper allmodconfig drivers/i3c/master.o
drivers/i3c/master.c:2203:3: error: variable 'i2cdev' is uninitialized when used here [-Werror,-Wuninitialized]
2203 | i2cdev->dev = i2c_new_client_device(adap, &i2cboardinfo->base);
| ^~~~~~

I guess that report was missed because it was not actually addressed to
anyone?

FWIW, this patch appeared in a previous 5.15-rc release but Ben
rightfully pointed out it really was not necessary and Greg said he
would fix it up by hand:

https://lore.kernel.org/2026011724-florist-brook-5f1f@gregkh/

Guess that never happened?

Ping? I don't see 6cbf8b38dfe3 queued up in 5.15 and this continues to
break our builds:

https://github.com/ClangBuiltLinux/continuous-integration2/actions/runs/23093834605

Hm, I queued it up, but looks like Greg dropped it:

https://git.kernel.org/pub/scm/linux/kernel/git/stable/stable-queue.git/commit/?id=7c0d6910ad

I'm not sure why.
