Replace with:
"tpm_tis: Close all localities to ensure D-RTM compatibility
There are environments, for example, those that comply with the TCG D-RTM
specification that requires the TPM to be left in locality 2. Prepare
kernel for such environments by closing all the localities."
Please don't do anything to the code change (despite my one random
earlier comment).
