From d2e9d229cfbd73baf33a817a0212233cea7df59a Mon Sep 17 00:00:00 2001 From: Xu Wang Date: Fri, 3 Jan 2020 09:28:16 +0000 Subject: [PATCH] l2tp: Remove redundant BUG_ON() check in l2tp_pernet Passing NULL to l2tp_pernet causes a crash via BUG_ON. Dereferencing net in net_generic() also has the same effect. This patch removes the redundant BUG_ON check on the same parameter. Signed-off-by: Xu Wang Signed-off-by: David S.
