[for-next][PATCH 17/33] ftrace: Remove unused unregister_ftrace_function_probe() function

[Steven Rostedt <rostedt@goodmis.org>]

[-- Attachment #1: 0017-ftrace-Remove-unused-unregister_ftrace_function_prob.patch --]
[-- Type: text/plain, Size: 2613 bytes --]

From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>

Nothing calls unregister_ftrace_function_probe(). Remove it as well as the
flag PROBE_TEST_DATA, as this function was the only one to set it.

Signed-off-by: Steven Rostedt (VMware) <rostedt@goodmis.org>
