From: Jiri Olsa <[email protected]> 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.
