Subject[PATCH v1 0/3] tpm: prepare for TPM2
Date
This patch set fixes two race conditions in the TPM subsystem:

* Two-phase initialization for struct tpm_chip so that device can
initialize fully initialize before exposing itself to the user
space. Also, in future TPM2 devices must be flagged before they
can be registered.
* Machines where there are two TPM devices exposed by ACPI have
a racy lookup for the PPI interface. This patch set fixes this
issues

In addition, transmit_cmd() is renamed as tpm_transmit_cmd() and
made opaque so that separate command structure can be introduced
for TPM2.

Comments about v1:
* I think this could be pulled to 3.18 because this clearly fixes
bugs in the current implementation.

Jarkko Sakkinen (3):
tpm: merge duplicate transmit_cmd() functions
tpm: two-phase chip management functions
tpm: fix multiple race conditions in tpm_ppi.c
