Subject: [PATCH AUTOSEL for 4.14 09/60] crypto: lrw - Fix an error handling
path in 'create()'
From: Christophe Jaillet <christophe.jaillet@...adoo.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")
