Message-ID: <1327559803.28707.6.camel@joe2Laptop>
Date: Wed, 25 Jan 2012 22:36:43 -0800
From: Joe Perches <joe@...ches.com>
To: Dan Carpenter <dan.carpenter@...cle.com>,
Jiri Kosina <trivial@...nel.org>
Cc: kernel-janitors@...r.kernel.org, linux-kernel@...r.kernel.org
Subject: drivers: Use NULL not zero for pointer
Here are some assignments that should use NULL
not 0;
Done via script:
$ grep -rPl --include=*.[ch] "\bstruct\s+\w+\s*\*\s*\w+\s*\=\s*0\s*;" drivers | \
xargs sed -r -i -e 's/\b(struct\s+\w+\s*\*\s*\w+)\s*\=\s*0\s*;/\1 = NULL;/g'
