Subject: [PATCH 3/7] staging: media: Replace NULL with "!"
Date: Fri,  3 Mar 2017 01:21:58 +0530	[thread overview]
Message-ID: <1488484322-5928-3-git-send-email-singhalsimran0@gmail.com> (raw)
In-Reply-To: <1488484322-5928-1-git-send-email-singhalsimran0@gmail.com>

Use ! in comparison tests using "==NULL" rather than moving the
"==NULL" to the right side of the test.

Addesses multiple instances of the checkpatch.pl warning:
WARNING: Comparisons should place the constant on the right side of the
test
