James Bottomley 55707d531a tpm_tis: Add a check for invalid status ... Some TIS based TPMs can return 0xff to status reads if the locality hasn't been properly requested. Detect this condition by checking the bits that the TIS spec specifies must return zero are clear and return zero in that case. Also drop a warning so the problem can be identified in the calling path and fixed (usually a missing try_get_ops()).
