From: Jiri Olsa Date: Tue, 19 Jun 2012 15:47:52 +0000 (+0200) Subject: tracing/filter: Add missing initialization X-Git-Tag: upstream/snapshot3+hdmi~6017^2~72^2~1 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=92d8d4a8b0f4c6eba70f6e62b48e38bd005a56e6;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git tracing/filter: Add missing initialization 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.
