Subject: Re: [PATCH v5 0/7] TPM 2.0 support

I pushed couples of fixed in addition to these changes to:

https://github.com/jsakkine/linux-tpm2/tree/tpm2-v5

There was problem running self-test because the FIFO module that I have
seems to give me TPM2_RC_TESTING when I try to start the self-test.

Additionally. I was able to test force parameter for tpm_tis. Resources
are cleaned up properly at least for TPM2 devices.
