[PATCH v2] drivers/crypto/nx: saves chaining value from co-processor

[Michael Ellerman]

Hi Fin,

I don't know anything about crypto so I can only critique you on your
patch submission technique :)  ...

Ideally this should identify the commit, so:

  This bug was introduced in the original submission (v3.5), commit
  856d673 "powerpc/crypto: AES-CBC mode routines for nx encryption".

Including the subject of the commit is handy in case the patch has been
backported somewhere, in which case the commit sha will be different.

It should definitely be part of the commit message, not below the "---".

And Ben might disagree but I think with a clear cut bug fix like this it
should include the CC to stable, so:

    Cc: stable at vger.kernel.org # 3.5+

cheers
