From: Guillaume Nault Date: Fri, 6 Jan 2017 19:03:56 +0000 (+0100) Subject: l2tp: remove useless NULL check in __l2tp_ip*_bind_lookup() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=986f7cbc510e29c33b7c8c1701a902a752159425;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git l2tp: remove useless NULL check in __l2tp_ip*_bind_lookup() If "l2tp" was NULL, that'd mean "sk" is NULL too. This can't happen since "sk" is returned by sk_for_each_bound(). Signed-off-by: Guillaume Nault Signed-off-by: David S.
