[PATCH 2/3] tracing/filter: Add missing initialization
From: Steven Rostedt
Date: Tue Aug 07 2012 - 18:03:05 EST
From: Jiri Olsa <jolsa@xxxxxxxxxx>
Add missing initialization for ret variable. Its initialization
is based on the re_cnt variable, which is being set deep down
in the ftrace_function_filter_re function.
I'm not sure compilers would be smart enough to see this in near
future, so killing the warning this way.
