[PATCH] tpm: fix bug for TPM on ThinkPad T60 and Z60
The TPM chip on the ThinkPad T60 and Z60 machines is returning 0xFFFF for
the vendor ID which is a check the driver made to double check it was
actually talking to the memory mapped space of a TPM. This patch removes
the check since it isn't absolutely necessary and was causing device
discovery to fail on these machines.
