[PULL] TPM: MAINTAINERS contacts update and error report fix

[Rajiv Andrade <srajiv@linux.vnet.ibm.com>]

Hi James,

The following changes since commit 08162e6a23d476544adfe1164afe9ea8b34ab859:

  Yama: remove an unused variable (2012-04-23 17:20:22 +1000)

are available in the git repository at:
  git://github.com/srajiv/tpm.git for-james

The first as the subject implies is just a contacts update, and the second
makes the driver avoid to mistakenly report the disabled and deactivated TPM
states as an error.

Marcel Selhorst (1):
      MAINTAINERS: TPM maintainers' contacts update

Rajiv Andrade (1):
      TPM: chip disabled state erronously being reported as error
