I wanted to explore a more complete fix with delaying the testing
until all built-in registrations are complete but it turned out to
be too complicated for now.
So I think Tadeusz's patch is the simplest fix for 4.2. Could you
please test it to see if it makes your warning go away? Just in
case you're running into something else that happens to look the
same.
Here is his patch again with a corrected changelog.
Thanks!

Subject: crypto: aesni - fix failing setkey for rfc4106-gcm-aesni
rfc4106(gcm(aes)) uses ctr(aes) to generate hash key. ctr(aes) needs
chainiv, but the chainiv gets initialized after aesni_intel when both
are statically linked so the setkey fails.
This patch forces aesni_intel to be initialized after chainiv.
