Small TEE updates for v6.16

The second patch looks like it should be a bugfix for 6.15 instead, any reason to have it only in 6.16?
FWIW, it's more of a cleanup than a real bugfix; there is an unsigned integer wraparound, but if that occurs, we're guaranteed to hit a memory allocation bailout pretty much immediately afterwards. So I think putting it in 6.16 is reasonable.
