There's more than one function in Linux - maybe you'd rather want
to write: "tpm2_key_encode() allocates ..."

You can just write "it is never freed, which leads to a memory leak."
> Handle those cases with kfree().
"Free the memory chunk with kfree() in the return paths."

Thank you finding this and providing a fix, it is highly appreciated.
Please don't take the nitpicking with the language personally. Just want
to have it documented in appropriate form.
