Subject: [PATCH v7 0/2] Run TPM2_Shutdown on system shutdown
Date: Sun, 25 Jun 2017 14:53:22 -0700	[thread overview]
Message-ID: <> (raw)

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".

Since this bug can cause users to be locked out of their TPMs, I'd like
this patch included in at least 4.4 and 4.9. 4.1 is nice-to-have but not

gregkh Acked the proposal for stable in v3 of this patch.
