[PATCH 1/2] crypto: lrw - Fix an error handling path in 'create()'
From: Christophe JAILLET
Date: Sun Oct 08 2017 - 05:41:07 EST
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")
