Subject: [PATCH] fs-udf: Delete an unnecessary check before brelse()
Date: Tue, 3 Sep 2019 21:15:58 +0200	[thread overview]
Message-ID: <a254c1d1-0109-ab51-c67a-edc5c1c4b4cd@web.de> (raw)

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Tue, 3 Sep 2019 21:12:09 +0200

The brelse() function tests whether its argument is NULL
and then returns immediately.
Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
