From 51456b2914a34d16b1255b7c55d5cbf6a681d306 Mon Sep 17 00:00:00 2001 From: Ian Morris Date: Fri, 3 Apr 2015 09:17:26 +0100 Subject: ipv4: coding style: comparison for equality with NULL The ipv4 code uses a mixture of coding styles. In some instances check for NULL pointer is done as x == NULL and sometimes as !x. !x is preferred according to checkpatch and this patch makes the code consistent by adopting the latter form.
