Subject: [PATCH 2/4] crypto-ixp4xx: Two function calls less in
init_ixp_crypto() after error detection
From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sun, 15 Nov 2015 18:28:39 +0100
The dma_pool_destroy() function was called twice with a null pointer
if a "npe_error" was reported.
This implementation detail could be improved by the introduction
of another jump label.
