Subject: [PATCH v4 0/4] Optimize tpm2_read_public() calls

The main goal is fairly straight-forwrd here.

The aim of these patches is optimize the number of tpm2_read_public()
calls to the bare minimum. The last patch is a bit out of scope but
I included because it builds on top of this work.

Jarkko Sakkinen (4):
  KEYS: trusted: Re-orchestrate tpm2_read_public() calls
  KEYS: trusted: Store parent's name to the encoded keys
  KEYS: trusted: Open code tpm2_buf_append()
  tpm2-sessions: Enforce single authorized handle
