--- Comment #1 from Maxim Kochetkov <fido_max@inbox.ru> ---
It was fixed by:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/tools/objtool/check.c?h=v6.1-rc6&id=82880283d7fcd0a1d20964a56d6d1a5cc0df0713

You can apply patch or use newer kernel. 5.16.8 already has this fix.

--- Comment #2 from Dr I J Ormshaw <ian_ormshaw@waters.com> ---
Thanks,  5.16.8 isn't an option as there's no PREEMPT_RT patch available yet. 
I'll look at applying the patch below to 5.16.2
