Please include the full patch in the email unless it's huge, so others
don't need to jump through hoops to see the change.

Is this bug present in 2.6.37 and earlier?  If so, should we fix it in
those kernels?

<finds "tpm_tis: Use timeouts returned from TPM" on the mailing list>

OK, earlier kernels do need fixing.  Hopefully you included
"Cc: <stable@...nel.org>" in the changelog which we weren't shown.

That patch adds a new sysfs file but doesn't alter any documentation
file for it.
