[v2,0/3] Address !chip->auth

Message

Unless tpm2_sessions_init() is called, then chip->auth ends up being a null
pointer, which is ignored by authenticated sessions code. These patches aim
to fully address the bug, and hopefully still make into 6.10-rc7.

Tested on x86-64 with:

- TCG_TPM2_HMAC disabled.
- TCG_TPM2_HMAC enabled.
- TCG_TPM2_HMAC enabled, and "/* rc = tpm2_sessions_init(chip); */".

v2:
- Rebase to commit 8a9c6c40432e ("Merge tag 'io_uring-6.10-20240703' of git://git.kernel.dk/linux").
- Couple of cosmetic fixes.

Jarkko Sakkinen (3):
  tpm: Address !chip->auth in tpm2_*_auth_session()
  tpm: Address !chip->auth in tpm_buf_append_name()
  tpm: Address !chip->auth in tpm_buf_append_hmac_session*()
