@Rafał Miłecki, we just need an ack from you for the tee_bnxt_fw.c
change:

 https://lore.kernel.org/lkml/20210614223317.999867-9-tyhicks@linux.microsoft.com/

Jarkko just gave us an ack for tpm_ftpm_tee.c on the v4 series:

 https://lore.kernel.org/lkml/20210615130411.hvpnaxnhimjloiz3@kernel.org/

The patch tpm_ftpm_tee.c patch didn't change from v4 to v5 and the
underlying concept of not using TEE_SHM_DMA_BUF remained the same so I
don't think we need a separate v5 ack.
