Subject: [PATCH v1 0/2] Run TPM2_Shutdown on system shutdown
Date: Fri, 14 Jul 2017 12:57:59 -0700	[thread overview]
Message-ID: <20170714195803.7035-1-joshz@google.com> (raw)

This is a backport to the 4.4 stable kernel.

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
some other TPM maintainer's part

This patchset causes all devices in the tpm class to issue TPM2_Shutdown
when the system is shutting down.

As a prerequisite, it adds a "shutdown" method to "struct class".

Backporting to 4.4 since this bug can lock users out of their TPMs.
