[PATCH 0/3] tpm: Fix TPM 1.2 Shutdown sequence to prevent future TPM operations

[Jarkko Sakkinen]

commit db4d8cb9c9f2af71c4d087817160d866ed572cc9 upstream

This backport is for v4.14 and v4.19 The backport requires non-racy
behaviour from TPM 1.x sysfs code. Thus, the dependecies for that
are included.

NOTE: 1/3 is only needed for v4.14.
