From c5736a4067ad4c59d1447762172def7f27fe869a Mon Sep 17 00:00:00 2001 From: Quentin Lambert Date: Fri, 22 Jul 2016 15:32:41 +0200 Subject: crypto: ixp4xx - Add missing npe_c release in error branches Most error branches following the call to npe_request contain a call to npe_request. This patch add a call to npe_release to error branches following the call to npe_request that do not have it. This issue was found with Hector.
