From d1d9facfd1b326e0df587c96f0ee55de2ae9f946 Mon Sep 17 00:00:00 2001 From: James Morris Date: Fri, 1 Sep 2006 00:32:12 -0700 Subject: [PATCH] [XFRM]: remove xerr_idxp from __xfrm_policy_check() It seems that during the MIPv6 respin, some code which was originally conditionally compiled around CONFIG_XFRM_ADVANCED was accidently left in after the config option was removed. This patch removes an extraneous pointer (xerr_idxp) which is no longer needed. Signed-off-by: James Morris Acked-by: Masahide NAKAMURA Signed-off-by: David S.
