Subject: [PATCH 2/7] perf header: Delete an unnecessary check before the calling free_event_desc()

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

The free_event_desc() 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.
