Date: Sun, 15 Nov 2015 19:50:51 +0100 From: SF Markus Elfring <elfring@...rs.sourceforge.net> To: "David S. Miller" <davem@...emloft.net>, Herbert Xu <herbert@...dor.apana.org.au>, linux-crypto@...r.kernel.org Cc: LKML <linux-kernel@...r.kernel.org>, kernel-janitors@...r.kernel.org, Julia Lawall <julia.lawall@...6.fr> 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.
