Subject: [PATCH] NULL: remove other definition of NULL
Date: Wed, 13 Apr 2016 20:11:33 +0800	[thread overview]
Message-ID: <1460549493-13044-1-git-send-email-d-hp@163.com> (raw)

From: Du Huanpeng <u74147@gmail.com>

remove other definition of NULL, use
  #include <linux/stddef.h>
instead.
I use this command to search NULL definition,
  grep -R "define\s*\<NULL\>"
hope there are no more definition of NULL.
