[ Upstream commit db4d8cb9c9f2af71c4d087817160d866ed572cc9 ]
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.")

Jarkko: did you deal with the issues that came up in response to my
post? Are you happy with this going into 4.19 stable at this point?
I notice this has your Signed-off-by so maybe?
I think that is just the signed-off-by chain coming from the upstream patch.
Jarkko mentioned getting to the backports after Linux Plumbers, which is next
week.
