If you're ok with the backport of this commit, I can just add
db4d8cb9c9f2 on top.

Sure, I've already gave my promise to do that :-)

I think that the dependency in question is actually:

        2677ca98ae377 ("tpm: use tpm_try_get_ops() in tpm-sysfs.c.")

Which is tricky to backport. I think I'll drop this patch for now and
wait for your backport instead.
