[PATCH] tpm: return chip from tpm_register_hardware
Changes in the 1.2 TPM Specification make it necessary to update some fields
of the chip structure in the initialization function after it is registered
with tpm.c thus tpm_register_hardware was modified to return a pointer to the
structure. This patch makes that change and the associated changes in
tpm_atmel and tpm_nsc. The changes to tpm_infineon will be coming in a patch
from Marcel Selhorst.
