Subject: [PATCH 0/8] Detach TPM space code out of the tpm_transmit() flow

Make the changes that are needed to detach TPM space code from
tpm_transmit() flow so that we do no longer need nested tpm_transmit()
calls.

v2:
* Print tpm2_commit_space() error inside tpm2_commit_space()
* Error code was not printed when recv() callback failed. It is
  fixed in this version.
* Added a patch that removes @space from tpm_transmit().
* Fixed a regression in earlier series. Forgot to amend the change
  from the staging area that renames NESTED to UNLOCKED in tpm2-space.c.

Jarkko Sakkinen (8):
  tpm: use tpm_buf in tpm_transmit_cmd() as the IO parameter
  tpm: print tpm2_commit_space() error inside tpm2_commit_space()
  tpm: clean up tpm_try_transmit() error handling flow
  tpm: access command header through struct in  tpm_try_transmit()
  tpm: move tpm_validate_commmand() to tpm2-space.c
  tpm: encapsulate tpm_dev_transmit()
  tpm: move TPM space code out of tpm_transmit()
  tpm: remove @space from tpm_transmit()
