Subject: [PATCH 3.2 067/106] perf probe: Fix examples section of documentation

3.2.93-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: SeongJae Park <sj38.park@...il.com>

commit d89269a89ebb6a74512f3f40e89cd12017f60a75 upstream.

An example in perf-probe documentation for pattern of function name
based probe addition is not providing example command for that case.

This commit fixes the example to give appropriate example command.
