Subject: perf header: Delete an unnecessary check before the calling free_event_desc()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=4cc97614812e96c135e369f3d723fcda07d33437;p=linux-beck.git

perf header: Delete an unnecessary check before the calling free_event_desc()

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.
