Subject: [XFRM] xfrm_user: Fix return values of xfrm_add_sa_expire.
X-Git-Tag: v3.12-rc1~31297^2~10
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3a765aa528401c7aec2208f7ed1276b232b24c57;p=kernel%2Fkernel-generic.git

[XFRM] xfrm_user: Fix return values of xfrm_add_sa_expire.

As noted by Kent Yoder, this function will always return an
error.  Make sure it returns zero on success.
