Phew, good to hear, thank you!

There might be for some time more than usual merge conflicts in TPM
driver given making tpm_buf memory layout flat for the sake of being
able to use __free for of its allocations, and thus completely 
prevent any possible memory leaks from transient buffers.

Right, and also merge conflicts could happen also in trusted keys.

They are cheap to fix and I'll monitor this situation proactively,
and try to react fast.
