commit db4d8cb9c9f2af71c4d087817160d866ed572cc9 upstream
TPM 2.0 Shutdown involve sending TPM2_Shutdown to TPM chip and disabling future TPM operations. TPM 1.2 behavior was different, future TPM operations weren't disabled, causing rare issues. This patch ensures that future TPM operations are disabled.
Fixes: d1bd4a792d39 ("tpm: Issue a TPM2_Shutdown for TPM2 devices.")

What kernel version(s) is this for?
It would go to 4.19, we've recently reverted an incorrect backport of this patch.
Jarkko, why is this patch 3/3? We haven't seen the first two on the mailing list, do we need anything besides this patch?
-- Thanks, Sasha
It looks like there was a problem mailing the earlier patchset, and patches 1 and 2 weren't cc'd to stable, but patch 3 was.
