From 63159f29be1df7f93563a8a0f78c5e65fc844ed6 Mon Sep 17 00:00:00 2001 From: Ian Morris Date: Sun, 29 Mar 2015 14:00:04 +0100 Subject: ipv6: coding style: comparison for equality with NULL The ipv6 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.
