Subject: [PATCH 4.4 10/31] crypto: crypto4xx - remove bad list_del

4.4-stable review patch.  If anyone has any objections, please let me know.

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

From: Christian Lamparter <chunkeey@...glemail.com>

commit a728a196d253530f17da5c86dc7dfbe58c5f7094 upstream.

alg entries are only added to the list, after the registration
was successful. If the registration failed, it was never added
to the list in the first place.
