From: Steven Rostedt (VMware) Date: Fri, 3 Jan 2020 00:04:57 +0000 (-0500) Subject: tracing: Initialize val to zero in parse_entry of inject code X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=02f4e01ce710fe20d2e5548d52bfdea52efd09d1;p=openwrt%2Fstaging%2Fblogic.git tracing: Initialize val to zero in parse_entry of inject code gcc produces a variable may be uninitialized warning for "val" in parse_entry(). This is really a false positive, but the code is subtle enough to just initialize val to zero and it's not a fast path to worry about it. Marked for stable to remove the warning in the stable trees as well.
