[PATCH 3/4 (no gpg)] tracing: Fix bad parameter passed in branch selftest

From: Steven Rostedt
Date: Thu Jun 06 2013 - 18:32:43 EST


From: "Steven Rostedt (Red Hat)" <rostedt@xxxxxxxxxxx>

The branch selftest calls trace_test_buffer(), but with the new code
it expects the first parameter to be a pointer to a struct trace_buffer.
All self tests were changed but the branch selftest was missed.

This caused either a crash or failed test when the branch selftest was
enabled.
