[PATCH 09/11] perf probe: Delete an unnecessary check before the function call "strfilter__delete"

From: Arnaldo Carvalho de Melo
Date: Mon Jul 06 2015 - 11:42:25 EST


From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>

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.
