    crypto: skcipher - Allow givencrypt to be NULL · 21dbd96f
    Herbert Xu authored
    Currently for skcipher IV generators they must provide givencrypt
    as that is the whole point.  We are currently replacing skcipher
    IV generators with explicit IV generators.  In order to maintain
    backwards compatibility, we need to allow the IV generators to
    still function as a normal skcipher when the RNG Is not present
    (e.g., in the initramfs during boot).  IOW everything but givencrypt
    and givdecrypt will still work but those two will fail.
    Therefore this patch assigns a default givencrypt that simply
    returns an error should it be NULL.
