From 30ac4e2f54ec067b7b9ca0db27e75681581378d6 Mon Sep 17 00:00:00 2001 From: Antonio Quartulli Date: Mon, 22 Feb 2021 17:25:43 +0100 Subject: wireguard: avoid double unlikely() notation when using IS_ERR() The definition of IS_ERR() already applies the unlikely() notation when checking the error status of the passed pointer. For this reason there is no need to have the same notation outside of IS_ERR() itself. Clean up code by removing redundant notation. Signed-off-by: Antonio Quartulli Signed-off-by: Jason A.
