It *semantically* depends on

db4d8cb9c9f2 ("tpm: use tpm_try_get_ops() in tpm-sysfs.c.")

I.e. can cause crashes without the above patch. As a code change your
patch is fine but it needs the above patch backported to work in stable

So... either I can backport that one (because ultimately I have
responsibility to do that as the maintainer) but if you want to finish
this one that is what you need to backport in addition and then it
should be fine.
