Subject: [PATCH 2/3] tracing/filter: Add missing initialization
Date: Tue, 07 Aug 2012 18:01:08 -0400	[thread overview]
Message-ID: <20120807220303.733846871@goodmis.org> (raw)
In-Reply-To: 20120807220106.459308722@goodmis.org

From: Jiri Olsa <jolsa@redhat.com>

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.
