Hi Jarkko,
Were you able to merge my patches? If not can you give me a bit more
info about what git repo and branch you're working off of, so I can
try to get it to apply to the HEAD of that branch?
Thanks,
Josh

Sorry about the mess. I'm a bit swamped today, but I'll work on
cleaning up the patch formatting & commit message and fix the
compilation problem later today or tomorrow. (It did build on my
checkout of the tpmdd branch... guess I didn't pull in some important
change.)

This patchset causes all devices in the tpm class to issue TPM2_Shutdown

I had to manually apply a couple of cherry picks and resolve some merge
conflicts, so some of this may be worth a closer look and test on Jarkko's or

Hm, strange. I see them in the archives for linux-stable@, but not in
my inbox. Perhaps I forgot to Cc myself on those patches.
