Subject: tpm: Remove check for working TPM from TPM interrupt handler
X-Git-Tag: rel-1.10.0~139
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=15f192fbc765ce364bc93cd6c6c974a5bb32b854;p=seabios.git

tpm: Remove check for working TPM from TPM interrupt handler

Remove the check for a working TPM from the TPM interrupt handler. This then
allows the individual API calls to return information even if the TPM was not
working correctly. Some API calls will still run into the check.
