[PATCH v3 0/4] Have IMA find and use a tpm_chip until system shutdown

This series of patches converts IMA's usage of the tpm_chip to find a TPM chip initially and use it until the machine is shut down. To do this we need to introduce a kref for the tpm_chip that IMA and all other users of a tpm_chip hold onto until they don't need the TPM chip anymore. Stefan
