Merge tag 'tpmdd-next-6.10-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/jarkko/linux-tpmdd

Pull tpm fixes from Jarkko Sakkinen:
 "This fixes two unaddressed review comments for the HMAC encryption
  patch set. They are cosmetic but we are better off, if such
  unnecessary glitches do not exist in the release.

  The important part is enabling the HMAC encryption by default only on
  x86-64 because that is the only sufficiently tested arch.

  Finally, there is a bug fix for SPI transfer buffer allocation, which
  did not take into account the SPI header size"
