From 087377a4307e18225f6452af5e71fe763c088c4e Mon Sep 17 00:00:00 2001 From: Kylene Jo Hall Date: Thu, 25 May 2006 18:44:27 -0700 Subject: [PATCH] [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.
