Subject: [PATCH 09/11] perf probe: Delete an unnecessary check before the function call "strfilter__delete"
Date: Mon,  6 Jul 2015 12:41:29 -0300	[thread overview]
Message-ID: <1436197291-21625-10-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1436197291-21625-1-git-send-email-acme@kernel.org>

From: Markus Elfring <elfring@users.sourceforge.net>

The strfilter__delete() 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.
