Subject: WARN_ONCE triggered: tpm_tis: Add a check for invalid status
Date: Wed, 14 Oct 2020 19:57:43 +0200 [thread overview]
Message-ID: <ghsgagsnag.fsf@gouders.net> (raw)
On my laptop the check introduced with 55707d531af62b (tpm_tis: Add a
check for invalid status) triggered the warning (output below).
So, my laptop seems to be a candidate for testing.
