WARN_ONCE triggered: tpm_tis: Add a check for invalid status

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
