This patch improves the DOCSIS session creation as follows:
- it validates the security action type as well as the protocol before
  creating a session and now does this validation before allocating the
  session from the mempool

Fixes: fda5216fba55 ("crypto/aesni_mb: support DOCSIS protocol")

Nice, this is actually fixing a potential memory leak, so you could mention this in the commit message/title.

Apart from this:
