    Subject[PATCH 4.14 106/159] crypto: lrw - Fix an error handling path in create()
    Date
    4.14-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Christophe Jaillet <christophe.jaillet@wanadoo.fr>


    [ Upstream commit 616129cc6e75fb4da6681c16c981fa82dfe5e4c7 ]

    All error handling paths 'goto err_drop_spawn' except this one.
    In order to avoid some resources leak, we should do it as well here.

    Fixes: 700cb3f5fe75 ("crypto: lrw - Convert to skcipher")
