[PATCH 2 of 6] tpm: remove pci dependency
From: Kylene Jo Hall
Date: Tue Oct 25 2005 - 10:21:32 EST
Since the tpm does not have it's own pci id we have been consuming the
lpc bus. This is not correct and causes problems to support non lpc bus
chips. This patch removes the dependency on pci_dev from tpm.c The
subsequent patches will stop the supported chips from registering as pci
drivers.
