From b289ba5e07105548b8219695e5443d807a825eb8 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sun, 5 Jan 2020 18:36:07 +0100 Subject: [PATCH] gtp: simplify error handling code in 'gtp_encap_enable()' 'gtp_encap_disable_sock(sk)' handles the case where sk is NULL, so there is no need to test it before calling the function. This saves a few line of code. Signed-off-by: Christophe JAILLET Reviewed-by: Simon Horman Signed-off-by: David S.
